Question

A force of $4N$ acts on an object of mass $2kg$ in $X-$direction and another force of $3N$ acts on it in $Y-$direction. Hence, the magnitude of the acceleration of the object will be___.

• A. $1.5m{s}^{-2}$
• B. $2.0m{s}^{-2}$
• C. $2.5m{s}^{-2}$
• D. $3.5m{s}^{-2}$

Answer 1

The correct option is C $2.5m{s}^{-2}$

resultant force acting on it=$\sqrt{4^2+3^2}=5$N

$5=ma=2a$

$a=2.5m/s^2$
