Feeling of weightlessness in a satellite is due to
1 absence of inertia
2 absence of gravity
3 absence of accelerating force
4 free fall of satellite
Explanation:
Gravitation

Pseudo force also called fictitious force such as centrifugal force arises only in
1 Inertial frames
2 Non-inertial frames
3 Both inertial and non-inertial frames
4 Rigid frames

How much faster than its normal rate should the earth rotate about its axis so that the weight of the body at the equator becomes zero \(\left(\mathbf{R}=6.4 \times 10^{6} \mathrm{~m}, g=9.8 \mathrm{~m} / \mathrm{s}^{2}\right)\) (in times)
