Question

When a force is applied in north direction of magnitude $10N$ and another force is applied in south direction of same magnitude. The resultant magnitude of the two forces is

• A. zero
• B. 10
• C. 20
• D. Greater than zero

Answer 1

The correct option is A zero

Let in North direction $\hat{j}$ is positive.

$F_1=10N\hat{j}$,

$F_2=-10N\hat{j}$,

$\Rightarrow$ Resultant=$F_1+F_2=10\hat{j}+(-10)\hat{j}$= 0
