A body of mass 2kg is suspended from the ceiling of a lift with a light inextensible string. lf the lift moves upwards with acceleration of 2ms-2, calculate the magnitude of the tension in the string (g = 1Oms-2)

A body of mass 2kg is suspended from the ceiling of a lift with a light inextensible string. lf the lift moves upwards with acceleration of 2ms^-2, calculate the magnitude of the tension in the string (g = 1Oms^-2)

A 24N
B 20N
C 16N
D 4N
E 0N

The correct answer is C. 16N

T + ma = mg

T = mg - ma = 2 x 10 - 2 x 2 = 16N
