A capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has radius 12.0 cm ,
and the outer sphere has radius 14.0 cm . A potential difference of 100 V is applied to the capacitor. A)What is the energy density at r= 12.1 cm , just outside the inner sphere?
B)What is the energy density at r = 13.9 cm , just inside the outer sphere?
C)For a parallel-plate capacitor the energy density is uniform in the region between the plates, except near the edges of the plates. Is this also true for a spherical capacitor?
There are formulas related to energy density but i couldn't figure out the solution.I would be thankful for your helps.
As per energy conservation we know that the electrostatic potential energy of the charge system is equal to the initial kinetic energy of the alpha particle
So here we can write it as
now we know that
z = 79
here kinetic energy of the incident alpha particle is given as
After thorough researching, the net gravitational force Fnet acting on the earth in the sun-earth-moon system during the new moon and when the moon is located directly between the earth and the sun is 3.50x10^22 N. The correct answer to the following given statement above is 3.50x10^22 N.
