Question

Force F on a particle moving in a straight line varise with. distance d. Find the work done on the particle during it's displacement of 12m. ​

Answer 1

Answer:

12F

Explanation:

According to the given question,

Force = F

Distance, d = 12m

And we are asked to find the work done,

We know,

Work done = Force × displacement cosx

where x = the angle between force and displacement

Here particle is moving in a straight line, so its displacement and force are in the same direction.

• So, x = 0°

• And, cosx = 1

(As cos0° = 1)

Hence,

• Work done = F×12

• Work done = 12F ans.
