Question

Hi may I get help with explanation? Thank you

A 133 kg object and a 640 kg are separated by 0.735 m. Find the magnitude of the net gravitational force exerted by these objects on a 42.0 kg object placed midway between them. Submit Answer Tries 0/6 At an infinitely remote distance, the net gravitational force on the third mass from the other two will be zero. Is there a point along the straight line between the two masses with the same property? (Enter Y for yes, N for no). Submit Answer Tries 0/6 At what distance of the 133 kg object would that be? (Answer -1 m if there is no such point.) Submit Answer Tries 0/6

Answer 1

m- M3=428 m2 = 640kg O 0.795120; 735m — * m, 133kg F The Magnitude of Net grovitational force exerted by these objects on 42 kg is FNet = F2-F, = GM2 M3 - Gm, ma 12 (412) FNet = (6.67X18")(42) [640-133] " T0.735/22 h 1.052 X 10^9N 6) yes (M) m3 = 42 kg c) m, 133 het om2=640 kJ +0.735-x-2x ) Given Firet = F2 - F, =0 F = Fz Gim, mz = G m2 m3 (0.735-x)² x 0.135 - 2 = ( 133 = 0.456 0.735-x=0.456* x= 0.505 m. The Distance from 133 Kg is =0.735 -0.505 = 10.23 m
