Question

How much work is done when a force of 15N displaces a body by 8 m in the direction of the force applied. Answer in joule ​

Answer 1

Explanation:

Hello Mate!

Work Done = Force ● Displacement

( Remember = The Work Done is dot product of Force and displacement. )

Here, Force = 15 N

Displacement = 5 m

Point to note : The displacement in in direction of Force. This means that W ( Work Done ) will be positive.

W = 15 N × 5 m

W = 75 Nm or 75 J

\textsf{ \red{ Hence work done is 75 J }} Hence work done is 75 J

Answer 2

Given information :-

• Force applied = 15 N
• Displacement = 8 m

Formula Applied :-

• Work done = Force x displacement

Solution :-

=> Work done = 15 x 8

=> Work done = 120 N m or Joule

Therefore the work done by the force of 15 N to displace it 8 m is 120 Joule
