\mathrm{KE}=\mathrm{as}^2

where a is a constant. The magnitude of the force acting on the particle as a function of ' s ' is

Options

A $\frac{2 \mathrm{as}^2}{\mathrm{R}}$
B $\frac{2 \mathrm{as}^2}{\mathrm{~m}}$
C2as
D2 a s \sqrt{1+ $\left(\frac{s}{R}\right)^2}$

Correct answer

D. 2 a s \sqrt{1+ $\left(\frac{s}{R}\right)^2}$
