Answer:

Explanation:
The energy, E, from a capacitor, with capacitance, C, and voltage V is:


If we increase the Voltage, the Energy increase also:


The voltage difference:


Answer:

Explanation:
We are given that
Distance between plates=d=2.2 cm=


Using 
We have to find the magnitude of E in the region between the plates.
We know that the electric field for parallel plates





Where 
Substitute the values


Hence, the magnitude of E in the region between the plates=
Given :
Mass of box , m = 250 kg.
Force applied , F = 285 N.
The value of the incline angle is 30°.
the coefficient of dynamic friction is
.
To Find :
The speed with which the box is moving with, assuming it takes 4 seconds to reach the top of the incline.
Solution :
Net force applied in box is :

Acceleration ,
.
By equation of motion :

Therefore, the speed of box is 12.04 m/s.
Hence, this is the required solution.
