Answer 1

hey

I think the answer is D

☆ Doesn't change

Answer 2

let us consider initially the mass of each particle is100 g

so now m1=150g

m2=50g

F=k×m1m2/r^2

(F1/F2)=m^2/(m1m2)

F1/F2=(100×100)/(150×50)

F1/F2=100/75

F1/F2=4/3

F2/F1=3/4

(F2-F1)/F1=1/4

In percentage the value of force increases by 25%

so answer is c.
