Question

A block of mass $5kg$ is placed o a round horizontal plane. The coefficient of static and kinetic friction between the block and surface are $0.5$ and $0.3$ respectively. A force of $100N$ is applied at an angle ${30}^{\circ }$ with the horizontal is shown in the figure. The acceleration of the block will be $\left[g=10m/s^2\right]$.

• A. $\left(10-\sqrt{3}\right)\sqrt{3}m/s^2$
• B. $20m/s^2$
• C. Zero
• D. $10\sqrt{3}m/s^2$

Answer 1

The correct option is D $10\sqrt{3}m/s^2$
