Question

Strings and pulleys are massless and frictionless The relation
between accelerations of the blocks as shown in the figure is

(A) a2 = 6a1 (B) a1 =
6a2 (C) a1 = 3a2 (D) a2
= 3a1

In the figure shown, what will be the acceleration of the block B
if that of the A is 0 3 m/s2

(A) 0 15 m/s2 (B) 0 6 m/s2 (C) 0 3
m/s2 (D) none of these

Dear Student,

can solve one at a time soving 7if the accn of the block A is a then the accn of B is a/2hence the accn of the block B=0
32=0 15 m/s2Regards
