According to universal law of gravitation , F= G m1m2 / r2  here m1= m2= 1 and            r =10-1 m  , therefore F = 6.67* 10-11* 1 / (10-1)2 =6.67* 10-9N

Two spheres of masses 2M & M are initially at rest at a distance R apart due to mumal force of attraction they approach each other when they are at separation R/2 the acceleration of the centre of mass of spheres would be what is the answer of the question

According to newtons law of gravitation f=g m1m2÷r^2 
Now, here, m1=m2 both have mass 1kg and r=10^-1m 
Therefore, f=6.67×10^-11×1÷[10^-1]^2
F=6.67×10^-9N
