Consider a conical pendulum with a bob of mass m = 68.0 kg on a string of length L = 10.0 m that makes an angle of ? = 7.00° with the vertical. (Consider + to be towards the center of the circular path and + to be upward.)
(a) Determine the horizontal and vertical components of the force exerted by the string on the pendulum.
(b) Determine the radial acceleration of the bob.
A conducting sphere that carries a total charge of -9.1 µC is placed at the center of a conducting spherical shell that carries a total charge of +1.7 µC. The conductors are in electrostatic equilibrium. Determine the charge on the outer surface o..
