Question

Five coplanar forces (each of magnitude $20N$) are acting on a body. The angle between two neighboring forces have the same value. The resultant of these forces is necessarily equal to

• A. $20N$
• B. $20\sqrt{2}N$
• C. Zero
• D. none of these

Answer 1

The correct option is C Zero

As the angle between any two neighbouring forces have the same value which is $\frac{{360}^{\circ }}{5}={72}^{\circ }$
and all the forces are of equal magnitude.
Hence, their resultant is zero.
