Question1

The relatively high resistivity of dry skin, about, can safely limit the flow of current into deeper tissues of the body. Assume an electrical worker places his palm on an instrument whose metal case is accidently associated to a high voltage. The skin of the palm is about 1.5 thick.

Question2

There is a positive charge at a finite distance outside

1) Spherical conducting shell, and

2) Solid conducting sphere (both are uncharged).

How is an induced charge on the sphere distributed in each case? Make sure distribution obeys the fact that the electric field inside the sphere is 0.

Question3

A room has dimensions 2.82 m (height) × 4.62 m × 6.66 m. A fly starting at one corner flies around, ending up at the diagonally opposite corner.

(a) What is magnitude of its displacement?

(b) If fly walks rather than flies, what is length of the shortest path it can take?
