Willa, the cartoon witch, dusts her crystal ball with her silk scarf, causing it to become charged with 5.0 x 10^ -9 C. Willa then stares into the crystal ball and the wart on the end of her nose experiences an electric field strengths of 2200 N/C. How far is the trip of her nose from the center of the crystal ball?

The distance between the tip of her nose from the center of the crystal ball is 14.3 cm.

Explanation:

Given that,

Charge,

The end of her nose experiences an electric field strengths of 2200 N/C

It is required to find the distance between the tip of her nose from the center of the crystal ball. The formula of the electric field is given by :

r is distance

So, the distance between the tip of her nose from the center of the crystal ball is 14.3 cm.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
