The amount of energy transferred when 10C of charge passes through a potential difference of 20 V is the same as the energy needed to raise a 2kg mass through a distance x. Find the value of x, take the value of g as 10 m/s 2

Question

Philoid · Accepted Answer

Given:

Mass of the object = 2 kg,

Charge = 10 C,

Potential difference = 20 V,

Calculations:

We know that the Energy transferred which a charge q is moved through a potential difference V is given by

E = q . V

Where,

Q is the charge

V is the potential difference

Also gravitational potential energy stored in an object is given as:

E= m× g× H

Where,

M is the mass of the object,

G is gravitational acceleration,

H is the displacement,

As per the problem both are equal,

m.g.x = q. V

putting the values in tehequation, we get

2× 10× x = 10 . 20

x =

= 10 meters.
