A man in the lift weighs more, when the lift is
Accelerating upwards
Weight:
Explanation for Correct Option:
Option A is correct.
Explanation for Incorrect Options:
Option B:
Moving up with constant velocity: As the velocity is constant, there will be no acceleration of the lift and therefore, the weight of the man will remain the same.
Option C:
Accelerating downwards: When the lift is accelerating upwards, its acceleration will be a, which will be added to the acceleration due to gravity to calculate the resultant acceleration. Therefore, the weight is , due to which the person feels heavier.
Option D:
Moving down with constant velocity: As the velocity is constant, there will be no acceleration of the lift and therefore, the weight of the man will remain the same.
Hence, the correct option is option A.
