There is a trolley in which there is a fixed inclined surface on which a smooth block of mass $5 kg$ is placed. Two horizontal forces of magnitude $F_{1}$ and $F_{2}$ are applied on the trolley as shown to keep the trolley at rest. The value of $F_{1} - F_{2}$ is : (Assume there is no friction between the trolley and horizontal ground and $g = 10 m s^{- 2}$ )

Options:

Answer:

Solution:

There is a trolley for which

$F_{1} + N \sin 37 ° = F_{2}$

$F_{1} - F_{2} = [- N \sin 37 °]$ . . . (1)

$N = [m g \cos 37 °]$ . . . (2)

$F_{1} - F_{2} = - m g \cos 37 ° \sin 37 °$

$= - 5 \times 10 \times \frac{4}{5} \times \frac{3}{5} = - 24 N$
