A block is placed on the top of a smooth inclined plane of inclination \(\theta\) kept on the floor of a lift. When the lift is descending with a retardation a, the block is released. The acceleration of the block relative to the incline is:
- g sin \(\theta\)
- a sin \(\theta\)
- (g –a) sin \(\theta\)
- (g + a) sin \(\theta\)
Answer
(D) (g + a) sin
