Derive+how+does+the+value+of+gravitational+force+f+between+two+objects+change+when+a)+distance+betweenthem+is+reduced+to+half+b)+mass+of+an+objectis+increase+four+times

Answer 1

Answer:

Explanation:

original force=GMm/$D^{2}$

(i)NEW FORCE=F/2

$\frac{f}{2} =\frac{GMm}{D^{2} }$

f=$\frac{2GMm}{D^{2} }$

ans. gravitational force is doubled

(ii)new mass=4m

f=$\frac{GM4m}{D^{2} }$

ANS. gravitational force increases 4 times
