to make it complex lets think of CONSTRAINT MOTION

now if you are scared enough just think of easier method

what strikes us now is LETS STOP C or in other word talk everything relative to C

now its sipmle two blocks A and B connected with a thread (which is inextensible) and by commonsense now velocity of block A relative to C will be equal to velocity of B relative to C

that is v1-v(knot)=v2

that is optionA

aprove if it helps you as it motivates me to answer more

Since in neither frame the string should break, the speed of blocks A and B along the string must be same in all frames.

Thus in the frame of block C, the speeds of blocks A and B along the string must be same.

Thus

v1 – v2 = v0

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
