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:

Options

  1. A- 2 i ^ - j ^ - k ^
  2. B4 i ^ + 2 j ^ + 2 k ^
  3. C2 i ^ + j ^ + k ^
  4. D2 i ^ + 3 j ^ + 3 k ^

Correct answer

C. 2 i ^ + j ^ + k ^

Step-by-step solution

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