Question

A force produces an acceleration of 4.5 cm/s² when it acts on a body of mass 24g . Find the force in S.I. unitA force produces an acceleration of 4.5 cm/s² when it acts on a body of mass 24g . Find the force in S.I. unit​

Answer 1

Answer:  1.08 *10^{-3} N

Explanation:

Given:

• acceleration = $4.5 cm/s^2$
• mass of the body = $24g$

To find:  Force (in SI unit)

Solution:

We know that,

the SI unit of Force is Newton (N) which is $kg$ $m/s^2$

So, we convert the quantities into SI units,

and get,

acceleration of the body = $4.5 cm/s^2$ = $4.5*10^{-2} m/s^2$ , and

mass of the body = $24g = 24 * 10 ^{-3} kg$

∴ Force = mass * acceleration

=> Force = $[24 * 10^{-3}] * [4.5*10^{-2} ] = 1.08 * 10^{-3} N$

The force in the SI unit is $1.08 * 10^{-3}$ Newton.
