A projectile is thrown with an initial velocity of `(a hati + hatj) ms^(-1)`. If the range of the projectile is twice the maximum height reached by it, then

A

`a = 2b`

B

`b = a`

C

`b = 2a`

D

`b = 4a`

Text Solution

Verified by Experts

The correct Answer is:
C
`R = 2H` or `(2u_(x)u_(y))/(g) = (2u_(y)^(2))/(2g)`
or `2u_(x) = u_(y)` or `2a = b`
