Answer:
The speed of the object is increasing.
F = M a as long as the magnitude of the acceleration is acting towards the right there will be an acceleration towards the right
Answer:F/4
Explanation:
F1=G M1M2/R^2
F2=G M1M2/4R^2 (1/2*1/2)
F1/F2=G M1M2/R^2 *G M1M2/4R^2
NOW everything gets canceled and we are left with-
F1/F2=4
F1/4=F2
so Option a is right.
