[2 marks] 2. Charged spheres X (2.4 x 10-C) and Y (4.5 x 10-7C) are in a set position. Calculate the net force on sphere Z, of charge -3.8 x 10-7C. [3 marks] X Y N O 6.00 cm 10.0 em 3. Calculate the electric field 0.8 m from a small sphere with a negative charge of 4.7 x 10-2C. [Note: Direction is inwards or outwards] [2 marks] Page8 4. In a Millikan-type experiment, two horizontal parallel plates are 1.0 cm apart. A sphere of mass 2.2 x 10-13 kg remains stationary when the potential difference between the plates is 350 V with the upper plate negative. [5 marks] (a) Is the sphere positively or negatively charged? Explain. (b) Calculate the magnitude of charge on the sphere.[cl How much excess or deficit of electrons does the sphere have? 5. A charged sphere with a charge of 3.? x III'6' experiences an electric force of [1.004 N [right I. Determine the magnitude and direction of the electric field that the charged sphere is in. [2 marks]
