A man of mass 60 kg is standing in a lift moving up with a retardation of \(2.8 \mathrm{~ms}^{-2}\). The apparent weight of the man is
- A 756 N
- B 168 N
- C 588 N
- D 420 N
Answer & Solution
Correct Answer
(D) 420 N
Step-by-step Solution
Detailed explanation
\(N = m(g - a)\) \(N = 60 \times (9.8 - 2.8)\) \(N = 60 \times 7.0\) \(N = 420 \text{ N}\)
