Instead of buying a capacitor, you decide to make one. Your capacitor consists of two circular metal plates, each with a radius of 10 cm. The plates are parallel to each other and separated by a distance of 2 mm. You connect a 12 volt battery across the plates. Find: the capacitance of the capacitor, the charge on each plate and the excess number of electrons on the negative plate. (To get the excess number of electrons, divide the charge on the plate to the basic unit of electric charge)

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

4. Instead of buying a capacitor, you decide to make one. Your capacitor consists of two
circular metal plates, each with a radius of 10 cm. The plates are parallel to each other
and separated by a distance of 2 mm. You connect a 12 volt battery across the plates.
Find: the capacitance of the capacitor, the charge on each plate and the excess number of
electrons on the negative plate. (To get the excess number of electrons, divide the charge
on the plate to the basic unit of electric charge)
