Question

A fellow scientist heard that a Van de Graaff generator built 70 years ago could collect 5.0 C of charge on its dome, which had a radius of 1.1 m, and has challenged you to do the same. You plan to use the same dome with the same radius and the belt you plan to use is 100 mm wide and 10.0 m long (5.0 m to go up to the dome, and 5.0 m to come back down). Charging the belt gives it a surface charge density of 65 C/m2 . Assume that the belt is being charged at a distance of half of the belt length from the center of the dome.

If you had more freedom in the design, what changes would you make to make the charging process easier on your motor, i.e. to reduce the force that should be exerted on the belt?

Check all that apply:

Increase the belt length. Decrease the belt length. Increase the belt width. Decrease the belt width. Increase the surface charge density on the belt. Decrease the surface charge density on the belt. Increase the dome radius. Decrease the dome radius.

Explanation / Answer

In order to increase the charging process , these changes should be recommended-

Thankyou.
