Question

Two blocks of masses $3kg$ and $2kg$ are placed side by side on an incline as shown in Fig. A force $F=20N$ is acting on $2kg$ block along the incline. The coefficient of friction between the block and the incline is the same and equal to $\mathrm{0.1.}$ Find the normal contact force exerted by $2kg$ block on $3kg$ block.

• A. $18N$
• B. $30N$
• C. $12N$
• D. $27.6N$

Answer 1

The correct option is C $12N$
