A boy pushes a book by applying a force of 40N.Find the work done by the force ,if the book is displaced by 25cm along the path.
25 cm = .25 m
work = force * distance in direction of force
= 40 * .25 = 10 Joules
10 j
Work done in 40N of 2m in 25
Force = 40N
Displacement = 25cm
25cm = 0.25m
Work done = Force x Displacement
W = F x s
W = 40 x 0.25
W = 10J
Hence, Work done is equal to 10J.

To find the work done, you can use the formula:
Work = Force x Distance
In this case, the force is 40N, and the distance is 25cm. However, it's important to note that work is typically measured in Joules (J), and the distance should be in meters (m) to match the unit of force. Therefore, we need to convert 25cm to meters.
1 meter is equal to 100 centimeters, so 25cm is equal to:
25cm / 100cm = 0.25m
Now we can calculate the work done:
Work = 40N x 0.25m
Work = 10J
Therefore, the work done by the force is 10 Joules (J).
