Answer:
-0.045 N, they will attract each other
Explanation:
The strength of the electrostatic force exerted on a charge is given by
where
q is the magnitude of the charge
E is the electric field magnitude
In this problem,
(negative because inward)
So the strength of the electrostatic force is
Moreover, the charge will be attracted towards the source of the electric field. In fact, the text says that the electric field points inward: this means that the source charge is negative, so the other charge (which is positive) is attracted towards it.
Answer:
Rate of change of area will be
Explanation:
We have given rate of change of radius
Radius of the circular plate r = 52 cm
Area is given by
So
Puting the value of r and
So rate of change of area will be
