Per NCERT, the MECHANICAL ADVANTAGE of an INCLINED PLANE of length L and height h is which expression?
AMA = L − h
BMA = L × h
CMA = L / h — the ratio of the inclined length to the vertical height
DMA = h / L
Answer & Solution
Correct answer: C. MA = L / h — the ratio of the inclined length to the vertical height
Per NCERT Eq. 7.13, MA of an inclined plane = L / h. Greater length (or smaller height) gives larger MA. The other formulas misstate.
