Question

Two weights w1 and w2 are connected by a light thread which passes over a light smooth pulley. if the pulley is raised up with acceleration equals to g then the tension in the thread will be

Answer 1

in this clause acceleration is negative ( T > mg ) as it oppose the gravity so tension in string with weight lesser than other will be more but here tension also depend on the surface area of the object .this can effect the tension wholly.
