A Spherical conducting shell is placed in a time varying magnetic field,is there an electric field along the equator?
Two metallic plates are separated by a distance of 0.030 m at a potential difference of 60 V. Between the equipotential surfaces, there is a potential difference of 3.0 V. Find the spacing in this part of the field between the two metal plates.
The source of electrons at a point is at the middle to two large metal plates 2 cm apart. One of the metal plates is maintained at 2 400 V above the other. Find (a) the potential gradient at the source measured at right angle to the plates and (b) the potential gradient at the source measured along a line to a point 15 cm from one plate.

Two circular loops And B have their planes parallel to each other,loop A has a current moving on the counterclockwise direction viewed from above.
(a)if the current in the loop A decrease with time,what is the direction of the induced current in the loop B.will the two loops attract or repel each other?
(b)if the current in loop A increases with time,what is the direction of induced current in loop B?,will the two loops attract or repel each other?
Which among the following factors have a profound effect on the reaction rate constant
When saving = Investment, show that the trade balance equals the government spendig balance
Loop A has a current moving in the counterclockwise direction, viewed from above.
1. If the current in loop A decrease with time, what is the direction of the induced current in loop B? Will the two loop attrack or repel each other.
