A point object moves along an arc of a circle of radius 'R'. Its velocity depends upon the distance covered 'S' as `V=K sqrt(S)` where 'K' is a constant. If `'theta'` is the angle between the total acceleration and tangential acceleration, then

Options

A. `tan theta= sqrt((S)/(R ))`
B. `tan theta = sqrt((S)/(2R))`
C. `tan theta = (S)/(2R)`
D. `tan theta = (2S)/(R )`

Answer

B
