Question

What is the magnitude of force needed to produce an acceleration of $4{ms}^{-2}$​ in a ball of $6kg$?

• A. $20N$
• B. $26N$
• C. $30N$
• D. $24N$

Answer 1

The correct option is D

$24N$

Given ,mass of ball, $m=6kg$ and acceleration a =$4{ms}^{-2}$.
Let force be $F$.
From Newton's second law of motion, $F=ma$
On substituting the values, we get,$F=6\times 4=24N$
$\therefore$ Force applied is $24N$.
