Per NCERT Example 7.12, a ramp raises a load over a 30 cm step and has a horizontal width of 40 cm. What is its MA?
AAbout 1.67 (since L = √(30² + 40²) = 50 cm, MA = L/h = 50/30 ≈ 1.67)
B2.0
C0.6
D1.0
Answer & Solution
Correct answer: A. About 1.67 (since L = √(30² + 40²) = 50 cm, MA = L/h = 50/30 ≈ 1.67)
Per NCERT Example 7.12, length L = 50 cm (3-4-5 triangle), height h = 30 cm, MA = 50/30 ≈ 1.67.
