A) \[\frac{{{p}^{2}}{{t}^{2}}}{3m}\]
B) \[\mu \,mg\sin \theta \]
C) \[\mu \,mgcos\theta +mg\sin \theta \]
D) \[\mu \,mgcos\theta -mg\sin \theta \]
Correct Answer: D
Solution :
The free body diagram showing the various force acting on the block are as follows The fractional force \[{{(Kg)}^{-2}}\] acts opposite to direction of motion of block, given by \[\Delta {{\mathbf{p}}_{1}}=-\Delta {{\mathbf{p}}_{2}}\] where R is reaction of the plane on block \[\Delta E=-\Delta (PE+KE)=0\] \[\mathbf{F}\Delta t=m\Delta \mathbf{v}\] \[\Delta \mathbf{x}\propto \Delta \mathbf{F}\] Resultant force upwards \[1:8\]You need to login to perform this action.
