Question

Consider the situation shown in figure, find the tension in string AB consider pulley
and string as frictionless and massless:
I kg A Blkg
u=0.5 u=0.5
10.3 kg
1) 3N
2) 2N
3) 8N
4) Zero

Answer 1

Answer:

1. same string same tension...different string different tensions
2. the system is moving together....so all individuals will have same acceleration
3. calculate the friction first...and see if it can balance the driving force

see the attachment first□□

now...as the friction is enough for opposing the motion...the system will not be move at all

no acceration

zero...
