. REMEMBER TO DRAW AND FULLY LABELLED DIAGRAMS WITH: O LABELS (m,v,F, ...... ) O MAGNITUDE o UNITS o DIRECTION o AN INDICATION of the positive (x and y) directions INCLUDE A SUMMARY SENTENCE . MAKE DIAGRAMS A REASONABLE SIZE'1. Charged spheres A( -4.0 x 10'6 C) and B (-2.5 x 10'? C) are fixed in position and separated by 10cm .Where between them is the net electric field zero? 2. An oil drop of mass 4.? x 10'15 kg is suspended between two parallel plates with a potential difference of 120 V and a separation of 5.0 mm between the plates. a) What is the charge on the oil drop? b) What number of elementary charges is required to get this charge
