Question

In the following options you are given the magnitudes of three forces in Newton acting simultaneously on a body. Find the set for which the resultant force on the body can be zero.

• A. $10,20,35$
• B. $15,30,14$
• C. $10,8,2$
• D. $40,19,17$

Answer 1

The correct option is C $10,8,2$

According to triangle law.
Triangle sum of two sides should be greater then third side.
Therefore, in each of the options $\left(b\right),\left(c\right)$and $\left(d\right)$, there is one force which is greater than sum of other two forces. Hence resultant force cannot be zero for these
