Question

When a force of 2 N causes a displacement of 70 cm the work done is *
​

Answer 1

${\tt{\blue{\underline{\underline{\huge{Answer:}}}}}}$

Given,

• Force(F)=2N
• Displacement (d)=70 cm
• Work done(W)=?

Now,

Changing the value of displacement into m.we get,

• Displacement (d)=70cm

=0.7m

Formula to be used:

• W=F × d

Again,

• Work done(W)=F × d

=(2 × 0.7)Joule

=1.4 Joule

Hence,When a force of 2 N causes a displacement of 70 cm the work done is 1.4 Joule.
