A psrticle is projected at `t = 0` with velocity u at angle `theta` with the horizontal. Then the ratio of the tangential acceleration and the radius of curvature at the point of projection is :

A

`(g^(2)sin2theta)/(u^(2))`

B

`(2g^(2)sin theta)/(u^(2))`

C

`(g^(2)sin theta)/(u^(2))`

D

`(g^(2)sin 2theta)/(2u^(2))`

Text Solution

Verified by Experts

The correct Answer is:
D
A particle is …………..
`(a_(1))/(R_(c )) = (g sin theta)/(u^(2)//g cos theta) = (g^(2)sin 2theta)/(2u^(2))`
