Question

32. What is the relation between speeds of blocks A and B in the given figure.
1) VB = VA
2) VB = 0.5VA
3) V8 = 2V
4) VB = 4VA
A​

Answer 1

The speed relation between the blocks is 3VA = VB.

Explanation:

• We are given that there are two blocks A and B.
• Thereofre, the relation between the blocks is given as  
• T(A) / T(B) = V(B) / V(A)
• Now put the value in the above relation it will become as.
• 3T / T = V(B) / V(A)
• After cancellation we get;
• 3 = V(B) / V(A)
• 3VA = VB
• Thus the speed relation between the blocks is 3VA = VB.
