a. Fd

b. –Fd

c. d/f

c. zero

Answer 1

Answer:

c . The work done by the driver is zero as there is only appliance of force but no displacement takes place .

Answer 2

Answer:

The work done by the driver will be zero.

Explanation:

First, let's understand what is work.

• Work is what we mean when we say that it is the product of force and displacement.

                                  $\mathrm{W=F.d}$                  (1)

Where,

W=work done by the body

F=force acting on the body

d=displacement of the body

Unless and until there isn't any displacement produced in the body the work done will remain zero.

So, the work done by the driver will be zero.

Hence, the correct answer among the given option is "Zero".
