Q11
Priya is writing some statements, choose the correct statement and help her:
[A]. Higher speed of an object moving through a fluid, greater will be the frictional force. Acting on it.
[B]. Larger the size of an object moving through a fluid, greater will be the frictional force acting on it.
[C]. Higher the viscosity or thickness of fluid, greater will be the frictional force or drag acting on an object moving through it.

[D]. Force of gravity is less than sliding friction
Q18
