The charge density of radius 12.0 cm isgiven by with a = 1.40 μC/m 3 and r ismeasured radially outward from theorigin. What is the electric potential atpoint A, a distance 40.0 cm above thedisk? Hint: you will need to integrate thenon uniform charge distribution to findthe electric potential.

The electric potential of the uniformly charge disk is 1392.1 V

Explanation:

Electric potential, for a uniformly charged disk at a distance A, is given as;

Where;

σ is the charge density = 1.40 μC/m³

ε is the permittivity of free space = 8.85 x 10⁻¹²

A is the distance above the disk = 40 cm = 0.4 m

R is the radius of the disk = 0.12 m

Substitute in these values into the equation above, we will have

Therefore, the electric potential of the uniformly charge disk is 1392.1 V

car stops. he keeps going = he has inertia

false

explanation:

boats, things on boats luggage are way more heavy then water.
