Two individual forces of magnitude $F_1$ and $F_2$, act on a body of mass 1 kg as shown in the figures (i) and (ii). If product of net magnitudes of forces produced in fig (i) and (ii) is 27N, then find the magnitude of forces $F_1$, and $F_2$. (assume $F_1>F_2$)

If $F_1$ is the magnitude of the force exerted on the Sun by Earth and $F_2$ is the magnitude of the force exerted on Earth by the Sun, then :

If $F_1$ is the magnitude of the force exerted on the Sun by Earth and $F_2$ is the magnitude of the force exerted on Earth by the Sun, then :

Two forces $F_1$ and $F_2$ acting on a body have a resultant $R_1$ if $F_2$ is doubled the$R_2$ new resultant forms are a right angle with $F_1$ Prove that $R_1$ and $F_2$ have the same magnitude.
