Question

find the force exerted on a mass of 20g if the acceleeation produced in it is 8 m per second square

Answer 1

Given :

Mass of the particle (m) = 20 kg

Acceleration of particle (a)= 8m/s²

To find :

Force exerted on the particle

Solution :

• Force exerted (F) = Mass × Acceleration

• F = m×a
• F = 20 × 8

• F=160 Nm/s²

The force exerted on the paricle is 160 Nm/s²

Answer 2

Given:

Mass of the particle (m) = 20 kg and

Acceleration of particle (a)= 8 $\dfrac{m}{s^2}$

To find: The force exerted on the particle (F) = ?

Solution:

We know that,

Force exerted (F) = Mass(m) × Acceleration(a)

⇒ F = m × a

∴ F = 20 kg × 8 $\dfrac{m}{s^2}$

⇒ F = 160 $\dfrac{kgm}{s^2}$ or, 160 N

∴ The force exerted on the particle (F) = 160 $\dfrac{kgm}{s^2}$ or, 160 N

Thus, the force exerted on the paricle is "160 $\dfrac{kgm}{s^2}$ or, 160 N".
