Question

A force of 10 N acts on a body in the upward direction and a force of 12 N acts on it in the downward direction Find the resultant of the forces acting on the body

• A. $2N$ , downwards
• B. $2N^3$ , downwards
• C. $2N^2$ , downwards
• D. $2N$ , upwards

Answer 1

The correct option is A $2N$ , downwards

$F_{resultant}=\overrightarrow{F_1}+\overrightarrow{F_2}$

$=-12\hat{j}+10\hat{j}$

$=-2\hat{j}$

$F_1=-12\hat{j}$

$F_2=10\hat{j}$

Resultant force is 2N, downwards
