The work done by a force acting on a body is as shown in the graph. The total work done in covering an initial distance

Options

A $225 \mathrm{~J}$
B $200 \mathrm{~J}$
C $400 \mathrm{~J}$
D $175 \mathrm{~J}$

Correct answer

B. $200 \mathrm{~J}$

Step-by-step solution

Area ABCEFDA = Area

\mathrm{ABCD}+

Area CEFD

The work done by a force acting on a body is as shown in the graph. The total work done in covering an initial distance

=\frac{1}{2} \times(15+10) \times 10+\frac{1}{2} \times(10+20) \times 5

=125+75=200 \mathrm{~J}
