A solid ball having a diameter 0.82m is to be raised on to step 32 cm high. If the roller weighs 50 kg-wt, find the minimum force that can be applied to the ball for that purpose (take g=10m/s^2)?

A solid ball having a diameter 0.82m is to be raised on to step 32 cm ...
Given data:
- Diameter of the ball = 0.82m
- Height of the step = 32cm = 0.32m
- Weight of the roller = 50 kg-wt
- Acceleration due to gravity, g = 10m/s^2
Calculating the minimum force:
Step 1: Calculate the weight of the ball:
The weight of the ball can be calculated using the formula:
Weight = Mass x Acceleration due to gravity
Given that the weight of the roller is 50 kg-wt, we need to convert it to kg by dividing it by the acceleration due to gravity:
Weight = 50 kg-wt / 10 m/s^2 = 5 kg
Step 2: Calculate the force required to lift the ball:
To lift the ball onto the step, the force applied should be equal to the weight of the ball plus the force required to lift it to the height of the step. The force required to lift the ball can be calculated using the formula:
Force = Weight + Mass x acceleration due to gravity x height
Substitute the values:
Force = 5 kg + 5 kg x 10 m/s^2 x 0.32 m
Force = 5 kg + 16 N
Force = 21 N
Therefore, the minimum force that can be applied to the ball to raise it onto the step is 21 N.
- Diameter of the ball = 0.82m
- Height of the step = 32cm = 0.32m
- Weight of the roller = 50 kg-wt
- Acceleration due to gravity, g = 10m/s^2
Calculating the minimum force:

Therefore, the minimum force that can be applied to the ball to raise it onto the step is 21 N.
