Question

During upward motion of a body projected vertically upward, the angle between velocity and 'g' is ${90}^{\circ }$.

• A. True
• B. False

Answer 1

The correct option is B False

Acceleration due to gravity $g$ always acts in the downward direction while the velocity vector points in upward or downward direction. Thus angle between velocity and $g$ is either $0^o$ or ${180}^o$ but not ${90}^o$. Thus the given statement is false.
