Answer:
easy answer 20 cm
Explanation:a²±b²=c² (12 cm)²±(16 cm)²=Z² 144 cm²+ 256 cm ²=Z² 400 cm²=Z² 20 cm= Z
The electric potential at the point P on the y axis at y = 12 cm is 20 cm.
The electric potential energy denoted by U is proportional to the charge and inversely proportional to the distance between the point where its is brought from infinity to the charge.
Given a charge per unit length given by l(x) = bx, where b = 12 nC/m2, is distributed along the x axis from x = +9.0 cm to x = +16 cm. if the electric potential at infinity is taken to be zero,
a²±b²=c²
(12 cm)²±(16 cm)²=Z² 144 cm²+ 256 cm ²=Z² Z = 20 cm
Thus, the electric potential at the point P on the y axis at y = 12 cm is 20 cm.
