I need this in 15 mns please

4) Two charges are separated by a distance of 20cm. a point exists 20 cm directly the point? above charge 1. If q1 = 5 * 10-6C and q2 = -2 * 10-6C what is the electric field at 6) A proton is placed in a region with a uniform, vertical electric field, with a magnitude such that the proton is in equilibrium under gravity and the electrostatic force. A proton weighs 1.6 * 10-27 kg, and has a charge of 1.6 * 10-19C. What is the magnitude of the electric field? -6 C of charge on capacitor? 6) An electron and a proton are separated by a distance of r=10cm in a region of space free of other charges and fields. The two charges are released from rest. What is the magnitude of the initial acceleration of the electron? [Useful values: the mass of the electron is me=9 * 10-31kg, and the magnitude of the charge on the proton and electron is e=1.6 * 10-19C.]
