a uniform electric field of 10 n/c exist in vertically downward directin. find the increase in the electric potential as one goes up through a height of 50 cm.

answered-by-expert Expert Answer
Change in electric potential = -E.ds where E is the uniform electric field and ds is the distance moved
Considering the upwards direction as +ve, hence E = -10N/C and ds = 50*10^-2 m 
Change in the electric potential = -(-10)*50*10^-2 = 5 V
 
Increase in potential as one goes 50cm upwards in a uniform electric field of 10N/c in downward direction is 5V.

A parallel-plate capacitor has a plate area of 100c * m ^ 2 and a plate separation of 2.0 cm. has been charged up to 3000 V by a battery. Now, (i) after disconnecting the battery, (ii) keeping the battery connected, the distance between the plates is increased to 5.0 cm intensity of electric field between the plates and the energy of the capacitor. ( epsilon_{0} = 8.85 * 10 ^ - 12 * F * m ^ - 1
