Assuming the Coulomb force supplies the necessary centripetal orle, m electrons speed v in its orbit about the nucleus. Find the value of the attractive Couloll 2 Can a charged object exert forces on an uncharged object? If so, will this force be attractive, repulsive, or is either possible? Explain your reasoning A stationary proton is released in a uniform electric field of 10,000 N/C as shown. Assuming the electrical force to be the only force acting on the proton (no gravity, air resistance, etc.), find the protons speed after traveling a distance of 10.0 cm. Which directio left or right? Hint: You may wish to review the kinematic equations in Ch. 2, page 56. 3. 4. A hollow, metallic sphere with a 25.0 cm radius carries a net charge of 20.0 uC. Assuming lertrstatic conditions, find the electric field value at the following distances from the
