Question

Acceleration of earth around sun in its orbit is always

a tengential b radial

Answer 1

Since the tangential velocity of the Earth around the Sun is constant (because all the years last the same for the orbit around the Sun), then the tangential acceleration will be zero.

This is the reason why the acceleration of the Earth around the sun in its orbit is always b) radial.
