Question

In the above question, find out the magnitude of net force exerted by the pulley on the road $R_1$

• A. $2F$
• B. $F$
• C. $2\sqrt{2}F$
• D. $\frac{F}{\sqrt{2}}$

Answer 1

The correct option is C $2\sqrt{2}F$

In the above question, find out the magnitude of net force exerted by the pulley on the road $R_1$.

$=2\sqrt{2}F$ where ,

$F=\frac{m{v}^2}{R_1}=\sqrt{2}\times (\sqrt{2}{)}^2\times F$

$=2\sqrt{2}F$ .
