We have three identical metallic spheres a, b, c. initially sphere a is charged with charge q, while b and c are neutral. first, sphere a is brought into contact with sphere b and then separated from it. after that, sphere a is brought into contact with sphere c and then separated from it. finally, sphere a is brought into contact with sphere b again, and then separated from it
what is final charge of sphere a?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
