Question

1. What happens to the potential energy between two point charges as their distances double?

drops to 1/4 of its original value

drops to 1/2 of its original value

remains unchanged

increases by a factor of 2

increases by a factor of 4

2. The electric charge for a conductor will always...

migrate toward the center of the conductor

sit on the outside surface of the conductor

distribute itself evenly inside the interior of the conductor

3. For a string, the node represents the position where the...

acceleration is maximum

displacement is the greatest

displacement is zero

tension is maximum

velocity is maximum

drops to 1/4 of its original value

drops to 1/2 of its original value

remains unchanged

increases by a factor of 2

increases by a factor of 4

parta) ans a (PE =k*q/r)

b) ansB (conductor cannot have a electric field inside)

c)ans C,D (node represent a place where amplitude=0 as a result tension is maximum at that point)
