Question

a body of mass 10kg is moved in a vertical circle calculate tangential acceleration

Answer 1

would call this a "trick" question

circular path means radial (centripetal) acceleration

there is no tangential component

Answer 2

Good

Answer 3

A body of mass 10 kg. It's moved in a vertical circle. When the body is at b then calculate it's tangential acceleration g= 10 m/ second square
