Question

A rack of seven spherical bolwing balls (each 7.00 kg, radius of 9.50 cm) is positioned along a line located a distance =0.850 m from a point ,
Calculate the gravitational force
the bowling balls exert on a ping-pong ball of mass 2.70 g, centered at point .

Answer 1

Answer:

8.72*$10^{-12}$ N

Explanation:

force of attraction f = G m1m2/ r^2 = $\frac{6.67*10^{-11}*7*5*2.70 }{.85*.85*1000}$ = 8.72*$10^{-12}$ N
