Answer:
Part a)
E = 0
Part b)
Part c)
Electric field inside the conductor is again zero
Part d)
Explanation:
Part a)
conducting sphere is of radius
R = 2 cm
so electric field inside any conductor is always zero
So electric field at r = 1 cm
E = 0
Part b)
Now at r = 3 cm
By Gauss law
Part c)
Again when we use r = 4.50 cm
then we will have
Electric field inside the conductor is again zero
Part d)
Now at r = 7 cm
again by Gauss law
In order to determine the angle of the refracted ray, we may apply Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is constant for a given wave when it passes through two different media. Mathematically, this is:
n₁sin(∅₁) = n₂sin(∅₂)
Where n is the refractive index. Substituting the values given into the equation:
1.0003 * sin(20°) = 1.33 * sin(∅)
∅ = 14.91
The angle of the refracted ray is 15°.
