Answer:
n=2.053
Explanation:
We will use Snell's Law defined as:
Where n values are indexes of refraction and values are the angles in each medium. For vacuum, the index of refraction in n=1. With this we have enough information to state:
Solving for yields:
Remember to use degrees for trigonometric functions instead of radians!
The magnitude of the electric field is , the direction is to the right
Explanation:
The magnitude of the electric field produced by a single point charge is given by
where:
is the Coulomb's constant
is the magnitude of the charge
r is the distance from the charge
In this problem, we have:
is the charge
r = 58 cm = 0.58 m is the distance of point P from the charge
Substituting, we find the magnitude of the field at point P:
The direction of the field for a positive charge is away from the charge: therefore, since point P is to the right of the charge, the direction of the field is to the right.
