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/s2
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.
