Most Important Selected Qs for JEE AdvancedPhysicsWork, Power and Energy
A block of mass m is pushed towards a movable wedge of mass n and height h , with a velocity u . All surfaces are smooth. Choose the correct statement from the following.
Options
- ABlock will reach top of the wedge if u= 2 g h (1- 1 n )
- BBlock will reach top of the wedge if u= 2 g h (1+ 1 n )
- CIf the block overshoots P , the angle of projectile is .
- DIf the block overshoots P , the angle of projectile is less than ,
Correct answer
D. If the block overshoots P , the angle of projectile is less than ,
Step-by-step solution
When the particle just reaches the top of the wedge aligned & m u=(m+n) v ...(1) & u= 2 g h (1+ 1 n ) aligned Angle of projection as observed by the ground will be loss than
