Help needed. (1) A small object carrying a charge of
experiences a downward force of 10 Newton when placed at a certain point in an electric field

What is the electric intensity at that point.

2. Determine the electric potential due to a charge of
at a point 6 cm from the charge.

3. A series arrangement of three capacitors of value at 8micro Farahds, 12 micro Farahds and 24 micro Farahds is connected in series with a 90—V battery
(a) Draw and open circuit diagram for this arrangement (b). Calculate the effective capacitance in the circuit

(c) On closed circuit calculate the charge on each capacitor when fully charged
(d) Determine the PD across the 8 micro Farahds capacitors.
