1 of 1

Application +4 | -1

A particle moving in a circle of radius

R

with a uniform speed takes a time

T

to complete one revolution. If this particle were projected with the same speed at an angle '

\theta

' to the horizontal, the maximum height attained by it equals

4R.

The angle of projection '

\theta

' is then given by:

View answer and explanation

Correct option: B

\mathrm{\theta } = {\sin ^{ - 1}}{\left( {\frac{{2g{T^2}}}{{{\pi ^2}R}}} \right)^{\frac{1}{2}}}

Option B (

\mathrm{\theta } = {\sin ^{ - 1}}{\left( {\frac{{2g{T^2}}}{{{\pi ^2}R}}} \right)^{\frac{1}{2}}}

) is correct because it relates the angle of projection to the time period, radius, and maximum height.
