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 net gravitational force on the mass at the origin is
- \(1.67 \times 10^{-9}(\hat{i}+\hat{j}) N\)
- \(3.34 \times 10^{-10}(\hat{i}+\hat{j}) N\)
- \(1.67 \times 10^{-9}(\hat{i}-\hat{j}) N\)
- \(3.34 \times 10^{-10}(\hat{i}-\hat{j}) N\)
Answer
(A) 1.67 10^ -9 ( i + j ) N
