Question

Force versus displacement graph is as shown in the diagram. The work done
by the force at the end of displacement 40 m is
(a) 20 J
(c) 100 J
(b) 40 J
(d) 80 J​

Answer 1

first a photo these chay

Answer 2

Answer:

(c) 100J

Explanation:

Area under force - displacement graph gives the work done.

Since we need the work done by the force only till the end of displacement 40m we will consider the first triangle in the graph.

Area= 1/2 × base × height

here,

base = 40m

height = 5 N

=》 Area = 1/2 × 40 × 5

= 100J
