An electroscope is a device which is used to find if an object is:

An electroscope is a device, which is used to test whether an object is charged or not. It consists of closely place two metallic strips. When both the strips are charged with similar charges, they repel each other and become wide open.

Which of the following cannot be charged by friction, if held by hand?

Here, all are insulators whereas “Copper rod” is a conductor. As soon as we charge a copper rod by rubbing with another material, the electric charge flow through our hand and body and flows into the earth. As a result, the copper rod remains un-charged.

When a glass rod is rubbed with a piece of silk cloth then:

When we rubbed a glass rod with silk cloth, the glass rod becomes positively charged. The silk cloth becomes negatively charged. The electric charges generated by rubbing are static electric charges. These electric charges remain bound on the surface of the charged object

Paheli is writing some statements, choose the incorrect statement and help her:

Here, all the statements are correct. Hence, your answer will be option [D].

The earth’s plate responsible for causing earthquake is:

An earthquake is a sudden shaking or trembling of the earth which lasts for a very short time. It is caused by the disturbance deep down inside the uppermost layer of the earth called crust.

Payal is completed her science chapter where she wrote some statements. She wants to know whether the statements are correct or not? Payel wants to take help from you:

Here, all the statements are correct. Hence, your answer will be option [D].

The magnitude of an earthquake is measured on:

The magnitude (or intensity) of an earthquake is expressed in terms of Richter scale.

Badal appeared in class test but he confused to know the incorrect statement. Would you help him to know that?

Here, all the statements are correct. Hence, your answer will be option [D].

The boundaries of the earth plate are known as:

Since earthquakes are caused by the movement of plates, the boundaries of the plates are weak zones where earthquake are more likely to occur. These weak zones are also known as seismic zones or fault zones.

When an object gets negatively charged by the process of friction then:

During a charging by rubbing (or by friction) process, the material that becomes negatively charged does so because it simply likes or gain electrons more than the material with which it is rubbed. The conductive abilities of the two materials has nothing to do with the subsequent result of the rubbing process.

In a science quiz competition, Payel is asked a question where she had to choose the statement which was/were incorrect?

The process of electric discharge occurs between the earth and the clouds and ultimately leads to the lighting.

When a plastic comb is rubbed with dry hair, the hair gets positively charged by friction. In this process:

When we comb dry hair with plastic comb, friction takes place between two objects. Due to friction, hair losses some electrons to plastic comb. Due to loss of electron, the hair becomes positively charged and due to gain of electron, plastic comb becomes negatively charged.

The place inside the earth's crust where the earthquake is generated is called:

Focus of an earthquake is located deep under the ground. Focus is the point inside the crust where the pressure is released. The point on the earth’s surface above the focus is called the epicenter.

Consider the following statements and choose the correct one:

Here, all the statements are correct. Hence, your answer will be option [D].

In a quiz competition, you are asked a question where you have to choose the statement which is/ are incorrect?

The whole crust of the earth is not in one piece. The crust of earth is made up of many huge pieces of flat rocks. Each pieces of the earth crust is called a plate. The crust of earth is divided into many plates. The plates of earth on which continents exist are called “continental plates” whereas those plates of earth on which oceans exist are called “oceanic plates”.
