Explanation:
Given
Voltage of battery 
electric field(E) is given by

i.e. Change in Potential over a distance x
(a)When Plate are separated by 3 cm apart


(b)When Plates are 5 cm apart


Force on electron is given by


For case a


(b)
Answer:
The atoms that contain an unstable combination of neutrons and protons, or excess energy in their nucleus
Answer:
The value of acceleration due to gravity is greater in terai than in mountain. In terai region the radius of earth is less as it lies close to the centre of the earth. Thus, the value of g is more in terai region.
An electromagnet is a type of magnet in which the magnetic field is produced using the current. The simplest form of an electromagnet is a wire wrapped around in a coil.
The strength of magnetic field of such magnet is given with this equation:

Where N is the number of loops in the coil, I is the strength of the current flowing through the coil, L is the length of the coil, and

is <span>permeability of the electromagnet core material.
From this equation, we can see that increasing both the current and number of loops will increase the strength of the magnet.
Both BLANKS should be
Increase. When you use the additional battery you will have more voltage and more voltage means more electricity.</span>
