To solve this problem it is necessary to use the concepts related to Snell's law.
Snell's law establishes that reflection is subject to
Where,
Angle between the normal surface at the point of contact
n = Indices of refraction for corresponding media
The total internal reflection would then be given by
Therefore the 
would be equal to
Therefore the largest value of the angle α is 30.27°
Answer:
The value of current generated would increase.
Explanation:
Electromagnetic induction is the process by which an electromotive force is induced due to a variation of magnetic field.
The induced current is directly proportional to rate at which the coil cuts the magnetic field. Using more powerful battery in the experiment would increase the rate at the the coil cuts the magnetic field, therefore increasing the rate of variation in the magnetic field. This effect would cause a greater deflection on the galvanometer's scale, showing an increase in the current generated.
This experiment proves that an alternating current can be produced from magnetic field.

Answer:
F = 3.6 x 10⁻²⁴ N
Explanation:
The force of attraction or repulsion between two charges is given by the Coulomb's Law. Coulomb's Law states that:
F = kq₁q₂/r²
where,
F = Electric Force between electrons = ?
k = Coulomb's Constant = 9 x 10⁹ N.m²/C²
q₁ = q₂ = Charge on electron = 1.6 x 10⁻¹⁹ C
r = distance between electrons = 0.8 cm = 0.008 m
Therefore,
F = (9 x 10⁹ N.m²/C²)(1.6 x 10⁻¹⁹ C)(1.6 x 10⁻¹⁹ C)/(0.008 m)²
<u>F = 3.6 x 10⁻²⁴ N</u>
