Question

A force of 10N displaces a body by 5m , the angle between force and displacement is 60degree , the work done by the force is

Answer 1

Answer:

f=10N

d=5m

A=60

Explanation:

w=f*d*cos(a)

w=10*5*60

w=50*60

w=300j

Answer 2

Given:

• Force = 10 N
• Displacement = 5 m
• The angle between the force and displacement = 60°

To Find:

• The work done by the force.

Solution:

The formula to find the work done by the force is given by,

W = F×s×cosθ → {equation 1}

Where "w" is the work done, "F" is the force, "s" is the displacement, and "cosθ" is the angle between the force and displacement.

On substituting the given values in equation 1 we get,

⇒ W = 10×5×cos(60) {multiplying the terms)

⇒ W = 50 × (1/2) {cos 60 = 1/2 and multiplying them}

⇒ W = 25 J

∴ The work done by the force = 25 J.
