Two fixed frictionless inclined planes making an angle 30º and 60º with the vertical are shown in the figure. Two blocks A and B are placed on the two planes. What is the relative vertical acceleration of A with respect to B?
Text Solution
Verified by ExpertsThe correct answer is:
D
Vertical component of acceleration of A
a 1 = (g sin θ ). sin θ
= g sin 60º. sin 60º = g. 
That for B
a 2 = g sin 30º. sin 30º = g 
∴ (a AB ) ⊥ = 
– 
= 
= 4.9 m/s 2
