Question

3.
A horizontal force 600 N pulls two masses 10 kg and 20 kg lying on a frictionless
table connected by a light string find tension in the string if the force is applied on
20 kg mass.
​

Answer 1

Answer:

Because the string is thin and inextensible, then: The general case (instead of mass 10kg and 20kg →m1 and m2, F= 600) Newton's second law for the mass m1: +1 vote answered Jun 16, 2018 by paayal (147k points) If the 20 kg mass is pulled, 600 - T = 20a, T = 10a a = 20ms-2, T = 200N If the 10kg mass is pulled, a = 20ms-2, T = 400NRead more on Sarthaks.com - https://www.sarthaks.com/75951/horizontal-force-pulls-masses-10kg-20kg-lying-frictionless-table-connected-light-string
