Solution
Awoodda korantada ee ku jirta gudbiyaha wareegsan = Awoodda korantada ee dusha sare ee gudbiyaha wareegsan.
La yaqaan:
Dareeraha korontada (Q) = 6.4 x 10-9 C
Gacanka gudbiyaha wareegsan (r) = OP + PQ = 4 cm + 5 cm = 9 cm = 9 x 10 -2 m
Joogtada Coulomb (k) = 9.10 9 Nm 2 .C -2
La Doonayo: Awoodda korantada ee barta P (V)
Xalka:
V = k Q / r
V = (9 x 10 9 )(6,4 x 10 -9 ) / (9 x 10 -2 )
V = 10 9 (6,4 x 10 -9 ) / 10 -2
V = 6.4 / 10 -2
V = 6.4 x 10 2
V = 6.4 x 100
V = 640 Volt
