Question

A body of mass 4 kg experiences two forces F → 1 = 5 i ^ + 8 j ^ + 7 k ^ and F → 2 = 3 i ^ - 4 j ^ - 3 k . ^ The acceleration acting on the body is:, - 2 i ^ - j ^ - k ^, 4 i ^ + 2 j ^ + 2 k ^, 2 i ^ + j ^ + k ^, 2 i ^ + 3 j ^ + 3 k ^

MARKS App · Accepted Answer

Net force F → = F → 1 + F → 2 = 8 i ^ + 4 j ^ + 4 k ^ Therefore, required acceleration a → = F → m = 2 i ^ + j ^ + k ^
