Two particles of masses and are connected by a light inextensible string over a smooth fixed pulley. Find the tension in the string. (Take .)
Answer and explanation
Correct answer: C.
- Step 1: Acceleration m s.
- Step 2: For the lighter mass: N.
Answer
.
Why not the others: is what you get if you use the weight of the heavier mass. is what you get if you use the weight of the lighter mass. is what you get if you forget the factor .
