1. A charge q = - 1.0 C is placed at (0, 0) m while another charge Q = 3.0 C is placed at (0.15, 0) m. Calculate the magnitude of the electric force acting on q.

The plates of a parallel plate capacitor 5.0*10—5m apart are maintained at a potential difference of 5.0*10—4v. Calculate the magnitude of the 1) electric field intensity on the surface of the sphere. 2)force of acceleration. 3) acceleration of the electron. Note. Electron charge =1.6*10—19c, Mass electron= 9.1*10—31kg
