Question

A force of $5N$ acts horizontally on a body of weight $9.8N$. What is the acceleration produced (in ${ms}^{-2}$)?

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

Answer 1

The correct option is D $5.00$

Suppose the mass of the body is $m$.

Weight of body $=mg$

Here,

$mg=9.8$

$\Rightarrow m=1kg$

So for acceleration,

$a=\frac{F}{m}$

$a=\frac{5}{1}$

$\Rightarrow a=5m{s}^{-2}$
