Question

A force of$5N$ acts on a body of weight $9.8N$. What is the acceleration produced in $m/s^2$?

• A. $49$
• B. $5$
• C. $1.46$
• D. $0.51$

Answer 1

The correct option is B

$5$

Step 1: Given data

Force, $F=5N$

Weight, $W=9.8N$

Step 2: Finding mass (m)

$\begin{array}{rcl}W& =& mg\\ 9.8& =& mx9.8\\ m& =& 1Kg\end{array}$

Step 3: Finding acceleration

Force is given by

$$\begin{gathered} F=ma \\ 5=1xa \\ a=5m/s^2 \end{gathered}$$

Hence, option B is correct.
