Dear student

vector c is not given hence I am only able to soleve nagle between a and b only.

- 10 + 8 – 24 = sqrt(77) sqrt (24) cos theta

hence cos theta = – 26/ sqrt(77) sqrt(24)

Dear student

Please provide the vector C

Because r = a+b+c

If we do not know C how can we calculate C ,

Later on the r can not be calculted .

So, provide the whole question .

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.
