Question

A force of 10 N acts on a object. The object is displaced through 12m in the direction of the force if the force acts all through the displacement find the work done by the force

Answer 1

Given,

force= 10N

Displacement= 12m

Work = F×s

= 10×12joule

= 120 joule.

Answer 2

Answer:

The work done by the force is 120 J

Explanation:

Given :

Magnitude of Force (F) = 10 N

Displacement (s) = 12 m

To Be Calculated :
The magnitude of Work Done by the force.

Solution:

Work Done by any force is given by the dot product of the magnitude of the force and displacement.

So, Work Done is a Scalar Quantity, it has only magnitude.

W = F.s = FsCos$\alpha$

Here, $\alpha$ is the angle formed between force's direction and displacement.

Here, force is applied in the direction of the force,

So, $\alpha$ =0

Thus, W = F*s = 10 *12 =120 J

Thus, the work done by the force is 120 J
