A toy car rolls down the inclined plane as shown in the fig. It goes around the loop at the bottom. What is the relation between 
and 
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
When car rolls down the inclined plane from height H, then velocity acquired by it at the lowest point
….(i)
and for looping of loop, velocity at the lowest point should be 
….(ii)
From eq n (i) and (ii) 
∴ ∴ 
.(iii)
From the figure 
⇒ ⇒ 
Substituting the value of r in equation (iii) we get 
⇒ ⇒
