Answer #1

Given Q 1 = 5 x 10 ^-6 C

Q 2 = 7 x10 ^-6 C

Q o = -3 x 10 ^-6 C

Potential at point A is V = [KQ1 / 14 cm ] +[KQ2 / 4cm] +[KQo/10.3 cm ]

= [KQ1 / 0.14 m ] +[KQ2 / 0.04m] +[KQo/0.103 m ]

Where K = 8.99 x 10 ⁹ Nm ²/ C ²

Substitute values you get V = (321071 ) + (1573250 ) - (261844)

= 1632476 volt

Similarly

Potential at point A is V ' = [KQ1 / 16 cm ] +[KQ2 / 6cm] +[KQo/12.3 cm ]

= [KQ1 / 0.16 m ] +[KQ2 / 0.06m] +[KQo/0.123 m ]

Where K = 8.99 x 10 ⁹ Nm ²/ C ²

Substitute values you get V ' = 280937.5 + 1048833 - 219268

= 1110502.5 volt

Potential difference = V ' - V
