JEE Main Physics question
The normal reaction on a body placed in a lift moving up with constant acceleration 2 ms⁻² is 120 N. The mass of the body is (take g = 10 ms⁻²)
Answer: (A)
Solution
R = m(g+a) ⟹ 120 = m(12) ⟹ m = 10 kg.
The normal reaction on a body placed in a lift moving up with constant acceleration 2 ms⁻² is 120 N. The mass of the body is (take g = 10 ms⁻²)
R = m(g+a) ⟹ 120 = m(12) ⟹ m = 10 kg.
