Question

please explain me how they have found out reaction at suspension point of pulley in this question ​

Answer 1

Answer:

Both blocks have been attached to same string passing through the pulley , so tension in both string will be same i.e. "T" . Now there are two forces on pulley in form of tensions , which are at exactly 90° to each other , therefore net force equals √(T^2 + T^2) = T√2
