Question

Calculate the work done by a 47 N force pushing a pencil 0.26 m.

Question 1 options:


12.2 J


180.77 J


0.005 J

Answer 1

the answer is the third option

Answer 2

The formula for work done is given by

W = f×d

Here W denotes the work done and is measured in Joules J

f= force and is measured in Newton N

d = is the displacement and is denoted in meters

Here we have f= 47; d = 0.26m

So we have

W = 47× 0.26

= 12.22J

Hence the option 1 is the right answer
