Question

force of 150 N applied on a body moves it through some distance.if the work done is 600 joules,find the displacement of body​

Answer 1

Answer :

›»› The displacement of a body is 4 m.

Given :

• Force applied on a body = 150 N.
• Work done by the body = 600 Joules.

To Calculate :

• The displacement of the body.

Calculation :

As we know that

→ W = Fs

Here,

• W is the Work done by the body.
• F is the Force applied on a body.
• s is the Displacement of a body.

Units,

• The unit of work done is Joules (J).
• The unit of Force is Newton (N).
• The unit of Displacement is Meter (m).

According to the given question,

We are asked to calculate the displacement of a body.

Therefore, we must calculate "s".

Given that,

• Force applied on a body = 150 N.
• Work done by the body = 600 Joules.

So,

• F = 150 N.
• W = 600 J.

Substituting the given values in the formula, we get:

→ 600 = 150 × s

→ 600 = 150s

→ 600 - 150s = 0

→ -150s = -600

→ 150s = 600

→ s = 600/150

→ s = 60/15

→ s = 4

Hence, the displacement of a body is 4 m.

Answer 2

Answer:

$\huge \bf \: given$

• Force of body = 150 N
• Work done = 600 Joule

$\huge \bf \: to \: find$

Displacement of body

$\huge \bf \: solution$

As we know that

$\huge \fbox { \bf w \: =fs} \bigstar$

Here

W = Work done

F = Force applied

S = Displacement

$\tt \implies \: 600 = 150 \times s$

$\tt \implies \: 600 = 150s$

$\tt \implies \: s = \dfrac{600}{150}$

$\tt \implies \: s \: = 4 m$

Here,

SI unit of work = Joules (J)

SI unit of Force = Newton (N)

SI unit of displacement = Metre (M)
