Question
The figure between shows two parallel plates. Assume they are infinite in area (this way we can neglect edge effects). The plate on the left is at a potential of +36V and the plate on the right is at a potential of OV. The plates are a stance 24cm apart and the dashed lines are spaced equally 6cm apart. Evaluate the following statements appropriately: greater than: The electric potential at point D is ___ the electric potential at point F. equal to: The electric potential at point B is ___ the electric potential at point E. greater than: The electric potential energy of a proton at point A is ___ the electric potential energy of an proton at point B. greater than: The electric potential energy of an electron at point B is ___ the electric potential energy of an electron at point A.Explanation / Answer
since the potential decreases as we move from positive plate to negative plate ,then
The electric potential at point D is greater than electric potential at point F
since B and E lie on the equipotential surface,then
Then electric potential at point B is equal to electric potential at point E
Electir potnetial energy is U = q*V
V is the potential at a point and q is the charge of proton
as V is greater then potential energy U is also greater
The electric potential energy of proton at a point A is greater than the electric potential energy of the proton at point B
For electron it will be reveresed
So the electric potential energy of electron at a point B is greater than the electric potential energy of the electron at point A
electric potential at point D is 27 V
Electric field at B is (18-36)/0.12 = 150 V/m
