A body of mass 10 kg is placed in a lift moving upward with an acceleration of 2m/s 2 . The apparent weight of body is (g = 9.8 m/s 2 )
Text Solution
Verified by ExpertsThe correct answer is:
A
Apparent weight of an object in a lift going upward with acceleration 'a' is
W' = m (g + a)
= 10 × (9.8 + 2)
= 10 × 11.8 = 118 newton
