Two forces $F_{1}$ \& $F_{2}$ of magnitude 12 N \& 5 N respectively are exerted on a body. $F_{1} + F_{2} = 13 N$ . If the angle between $F_{1}$ \& $F_{2}$ is 15 x (in degree) then fill the value of x in OMR sheet.

Answer:

Solution:

Given, $F_{1} = 12 N, F_{2} = 5 N$ $F_{1} + F_{2} = 13$ $∴ (13)^{2} = (12)^{2} + (5)^{2} + 2 \times 12 \times 5 cos θ$

$∴ θ = \frac{π}{2} = 9 0^{\circ}$
