In the figure shown, if coefficient of friction is \(\mu\), then m2 will start moving upwards if:
- \(\frac{m_{1}}{m_{2}}>\sin \theta-\mu \cos \theta\)
- \(\frac{m_{1}}{m_{2}}>\sin \theta+\mu \cos \theta\)
- \(\frac{m_{1}}{m_{2}}>\mu \sin \theta-\cos \theta\)
- \(\frac{m_{1}}{m_{2}}>\mu \sin \theta+\cos \theta\)
Answer
(B) m_ 1 m_ 2 > +
