Question

the given diagram shows the velocity - time graph of a particle of mass 100 g moving in a straight line. calculate the force acting in the particle. plz answer

Answer 1

a = slope of velocity time graph = 20/5=4 force=ma= 4*100/1000 (to convert gm into kg) F= 0.4N

Answer 2

Answer:

Force, F = 0.4 N

Explanation:

The given diagram shows the velocity - time graph of a particle of mass 100 g moving in a straight line.

The slope of the velocity time graph gives the acceleration of the particle i.e.

$slope=a=\dfrac{\Delta v}{\Delta t}$

So, $slope=a=\dfrac{20}{5}$

$slope=a=4\ m/s^2$

According to Newton's second law, the force acting on a particle is the product of its mass and acceleration i.e.

F = m a

F = 0.1 kg × 4 m/s²

F = 0.4 N

Hence, this is the required solution for the force acting in the particle.
