Answer:
(a) surface area of the plate will be equal to
(b) Charge on the capacitor is equal to
Explanation:
We have given spacing between the plates d = 0.05 mm =
Value of capacitance
(A) Capacitance of a parallel plate capacitor is equal to
So
So surface area of the plate will be equal to
(B) It is given that capacitor is charged by 1.5 volt
So voltage V = 1.5 volt
Charge on the capacitor is equal to
So
To solve this problem we will apply the linear motion kinematic equations. We will find the two components of velocity and finally by geometric and vector relations we will find both the angle and the magnitude of the vector. In the case of horizontal speed we have to
The vertical component of velocity is
Here,
h = Height
g = Gravitational acceleration
t = Time
= Vertical component of velocity
The direction of the velocity will be given by the tangent of the components, then
The magnitude is given vectorially as,
Therefore the angle is 55.59° and the velocity is 26.37m/s
