Answer:
The largest voltage is 0.02 V.
(d) is correct option.
Explanation:
Given that,
Range = 20 dB
Smallest voltage = 200 mV
We need to calculate the largest voltage
Using formula of voltage gain









Hence, The largest voltage is 0.02 V.
A) We need to calculate the Magnetic flux of a Solenoid,

Where B is the magnetic field and A the Area.

Here \mu_0 is the permeability constant, I the current and N number of turns.
Replacing we have,



B) We calculate the mutual inductance, so



c) We calculate the emf



Answer:
(a) 1000 N/C
Explanation:
Kinetic energy of electron, K = 1.6 x 10^-17 J
distance, d = 10 cm = 0.1 m
Let the potential difference is V and the electric field is E.
(a) The relation between the kinetic energy and the potential difference is
K = e V
V = K / e
Where, e be the electronic charge = 1.6 x 10^-19 C
V = 
V = 100 V
The relation between the electric field and the potential difference is given by
V = E x d
100 = E x 0.1
E = 1000 N/C
(b) The force acting on the electron, F = q E
where q be the charge on electron
So, F = -e x E
It means the direction of electric field and the force are both opposite to each other.
The direction of electric field and the force on electron is shown in the diagram.
