Question

Force of $5N$acts on a body of weight $9.8N$. what is the acceleration produced in $m{s}^{-2}$

• A. $49.00$
• B. $5.00$
• C. $1.46$
• D. $0.51$

Answer 1

The correct option is B

$5.00$

Step 1: Given data

Force (F) $=5N$

Weight of the body (W) $=9.8N$

Step 2: Find the acceleration

We know, $W=mg$, where “g" is the acceleration due to gravity and “m” is the mass.

$$\begin{gathered} 9.8=m\times 9.8 \\ m=1kg \end{gathered}$$

Force, $F=ma$, where “a” is the acceleration.

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

Hence the acceleration $a=5m/s^2$

Therefore the correct answer is Option B
