Question

Force F on a particle moving in a straight line varies with distance d as shown in the figure. work done on the particle during it's displacement of 12 m​

Answer 1

Answer:

force is the push and pull of an object it is also known as frictional

.

Answer 2

Answer:

W = 13 Joules

Explanation:

The given graph shows force distance graph. It can be calculated by taking the area under F-x graph.

Work done = Area of rectangle + area of triangle

Area of rectangle is :

$A_1=2\times (7-3)=8\ J$

Area of the triangle,

$A_2=\dfrac{1}{2}\times 2\times (12-7)=5\ J$

$A=A_1+A_2$

$A=8+5$

A = 13 J

So, the work done by the particle is 13 J. Hence, this is the required solution.
