Question

What is amount of Work Done if force ʽF makes an angle of ʽQ and covers a distance ʽdʼ​

Answer 1

Step-by-step explanation:

Work Done by a body is given by

Work Done (W) = Force (F) • Displacement (D)

[ Note • Represents Dot Product ]

W = F D cosΦ

In the question

Force = F

Distance = d

Angle = Q

Hence, Work Done

W = F d cosQ

Answer 2

Given:

The magnitude of force = F

The angle, θ = Q

The distance travelled = d

To Find:

The amount of Work Done.

Calculation:

- The amount of work done is given by the dot product of force and the distance travelled.

⇒ Work done = F . d

⇒ W = F d cos θ

- As θ = Q, we get:

⇒ W = F d cos Q

- So, the work done if force ʽF' makes an angle of ʽQ' and covers a distance ʽdʼ is (F d cos Q).
