- negative and distributed uniformly over its surface.
- negative and appears only at the point on the sphere closest to the point charge
- negative and distributed non-uniformly over its entire surface of the sphere
- zero
- planets and stars only
- point masses only
- big bodies only
- all bodies in the universe
- moment of inertia
- torque
- angular velocity
- mass
- There is no force of attraction or repulsion between the molecules of a gas
- The molecules of a gas are always in a state of random motion moving with all possible velocities in all directions
- The molecules of a gas due to their random motion collide with one another and also with the walls of the body
- All of these
- constant acceleration
- constant period
- proportionality between acceleration and displacement from equilibrium position
- proportionality between restoring force and displacement from equilibrium position
- same width
- different width
- uniform intensity
- non-uniform width & non uniform intensity
- the gravitational force acting on the astronaut is zero.
- acceleration due to the gravity of the earth is zero
- the astronaut is in an inertial frame of reference
- the floor of the satellite does not produce any reaction on the astronaut
