At the topmost point of a projectile trajectory, its velocity and acceleration are an angle of

A

`0^(@) `

B

`90^(@)`

C

`45^(@)`

D

`180^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
At the uppermost point of a projectile, the vertical component of the velocity of projection become zero, while the horizontal component remains constant . And the acceleration ( due to gravity ) is always vertically downwards . Therefore at the uppermost point of a projectile, its velocity and acceleration are at an angle of ` 90^(@)` .
