Answer 1

Answer:

Explanation:

in circular motion gravitational force is equal to centripetal force

$\frac{Gm_{1}m_{2} }{R^{2} } = \frac{m_{1}v^{2} }{R}$

so, $v^{2} = \frac{Gm_{2} }{R}$

kinectic energy = $\frac{1}{2}m_{1}v^{2}$

K.E. = $\frac{Gm_{1}m_{2} }{2R}$

Answer 2

holla dude !! prefer pic above of that qn... of electron.
