MCQ
A block is lying on an inclined plane which makes $60^{\circ}$ with the horizontal. If coefficient of friction between block and plane is $0.25$ and $g=10 \mathrm{~m} / \mathrm{s}^2$, then acceleration of the block when it moves along the plane will be
- A$2.50 \mathrm{~m} / \mathrm{s}^2$
- B$5.00 \mathrm{~m} / \mathrm{s}^2$
- ✓$7.4 \mathrm{~m} / \mathrm{s}^2$
- D$8.66 \mathrm{~m} / \mathrm{s}^2$
