Question

Point charges -9 microcoulomb, -20 microcoulomb, 10 microcoulomb are placed at the corners A B and C of a triangle ABC. If AB= 0.05m BC= 0.04m and CA= 0.03m. Calculate the resultant force on charge at C​

Answer 1

Answer:

In the arrangement of capacitors shown in Figure, if each capacitor is 9 pF, the effective capacitance between A and B is
