JEE Main 2024 (Online) 31st January Evening Shift Physics - Laws of Motion Question 5 English

A block of mass $$5 \mathrm{~kg}$$ is placed on a rough inclined surface as shown in the figure. If $$\overrightarrow{F_1}$$ is the force required to just move the block up the inclined plane and $$\overrightarrow{F_2}$$ is the force required to just prevent the block from sliding down, then the value of $$\left|\overrightarrow{F_1}\right|-\left|\overrightarrow{F_2}\right|$$ is : [Use $$\left.\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2\right]$$

A
$$5 \sqrt{3} N$$
B
$$\frac{5 \sqrt{3}}{2} N$$
C
$$10 \mathrm{~N}$$
D
$$25 \sqrt{3} N$$
