Question

Calculate the gravitational force between a 20 kg ball and a 40 kg ball placed at a separation of 10cm.​

Answer 1

Explanation:

gravitational force = G*M1*M2/r^2

= 6.67*10^-11*20*40/0.1^2

= 5336*10^-9 = 5.33*10^-6 N

Answer 2

Answer:

for 20kg ball is 20*9.8=x

for 40kg ball is 40*9.8=y

after the results multiply with 10.
