Question
Three identical point masses, each of mass 1 kg lie in the x-y plane at points (0, 0) (0, 0.2m) and (0.2m,0). The gravitational force on the mass at the origin is : -
Options
A.1.67 × 10-11 (î + ĵ)N
B.3.34 × 10-10 (î + ĵ)N
C.1.67 × 10-9 (î + ĵ)N
D.3.34 × 10-10 (î + ĵ)N
Solution
F1 = F2 = 
= 1.67 × 10-9
= F1 (î) + F2 (ĵ) 1.67 × 10-9 (î + ĵ)
= 1.67 × 10-9= F1 (î) + F2 (ĵ) 1.67 × 10-9 (î + ĵ)Create a free account to view solution
