Assertion: A block rests on a fixed smooth inclined plane of angle . The normal reaction on the block is m g .
Reason: The block has no acceleration perpendicular to the plane surface.
Options:
Answer:
A
Solution:
With no acceleration perpendicular to the plane, forces balance along the normal: (Assertion true);
the Reason gives exactly the condition that makes this balance valid, so it explains the Assertion.
