For what value of \(\theta\) are the forces in the diagram above in equilibrium
The fig above shows a block of mass m sliding down a rough inclined plane QP at angle \( \theta \) . The forces acting on the block along QP are
A uniform light beam XZ is Hinged at X and kept in equilibrium by the forces T and F as shown in the diagram above. if XO = 20cm and OY = 30cm, express T in terms of F
The diagram above shows two wave forms P and Q at a particular instant in time. the two waves will interface
