Question

Tow bodies A (30 kg) and B (50 kg), tied with a light string, are placed on a frictionless table. A force F

acting at B pulls this system with an acceleration of 2ms­2. The tension in the string is :

a) 40 N b) 100 N

c) 35 N d) 140 N​

Answer 1

Answer:60N

Explanation

F=ma

F=80×2 =160

F-T =ma

160-T =100

T=60N
