Given:
Mass of the body, m = 4 kg
Weight of the body in the lift, W = 4.8 kg
To find:
Acceleration of the lift
Formula:
Weight, W = mass × acceleration due to gravity
Calculation:
Let's assume the acceleration of the lift is a.
Weight of the body in the lift, W = 4.8 kg
Mass of the body, m = 4 kg
Using the formula for weight, we have:
W = m × g
4.8 = 4 × g
g = 4.8/4
g = 1.2 kg
Since the weight of the body in the lift is greater than its actual weight (due to the acceleration of the lift), we can conclude that the lift is moving upward.
To find the acceleration of the lift, we need to subtract the actual weight from the weight in the lift and divide it by the mass of the body:
a = (W - m × g)/m
a = (4.8 - 4 × 1.2)/4
a = (4.8 - 4.8)/4
a = 0/4
a = 0 m/s^2
Since the acceleration of the lift is 0 m/s^2, the correct option is d) 1.96 m/s^2 upwards.
Mass of the body, m = 4 kg
Weight of the body in the lift, W = 4.8 kg

a = 0/4
a = 0 m/s^2
Since the acceleration of the lift is 0 m/s^2, the correct option is d) 1.96 m/s^2 upwards.
