Question

The drawing shows three particles far away from any other objects and located on a straight line. The masses of these particles are m_4 = 363 kg, and m_c = 154 kg. Fend the magnitude and direction of the net gravitational force acting on each of the three particles (let the direction to the right be positive) particle A N particle A N particle A N A space traveler weighs 560 N on earth, what will the traveler weigh on another planet whose radius is three times that of earth and whose mass is twice that of earth?

Answer 1

Ans-  r1 = 0.5 m
r2 = 0.25 m
r3 = r1 + r2

Fa = (G mA mB / r1 ^ 2) + (G mA mC / r3 ^ 2)
Fa = 5.672*10^-5 >right

Fb = (G mA mB / r1 ^ 2) - (G mB mC / r2 ^ 2)
Fb= 3.491*10^-5 N >right

Fc = (G mA mC / r3 ^ 2) + (G mB mC / r2 ^ 2)
Fc = 9.163*10^-5 N <left
