STATEMENT-1: When speed of projection of a body is made n-times, its time of flight becomes `n` times.
STATEMENT-2: This is because range of projectile become `n` times.

A

Statement -1 is True, Statement-2 is Ture, Statement-2 is a correct explanantion for Statement-1.

B

Statement-1 is Ture, Statement-2 is Ture, Statement-2 is Not a correct explanantion for Statement-1.

C

Statement-1 is True, Statement-2 is False.

D

Statement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
C
As `T = (2usin theta)/(g) :. T' = (2nusin theta)/(g) rArr`
`T'= nT`
`R = ucos theta T:. R' = nu costheta T:. R' = n cos theta. nT rArr R' = n^(2) R`
