Answer:
Explanation:
q1 = - 4.7 x 10^-9 C
q2 = - 9.7 x 10^-9 C
q3 = 7.2 x 10^-9 C
Potential at the centre of the circle, V = - 1900 V
Let the radius of the circle is r.
So, the potential is given by
r = 0.034 m = 3.4 cm
<h3><u>Answer;</u></h3>
<em>When a wave meets a boundary, the angle of the reflected wave is equal to the angle of the incident wave</em>
<h3><u>Explanation</u>;</h3>
- <em><u>Reflection is the property of waves in which the waves bounces back upon meeting or hitting the surface of an object or a boundary.</u></em> It may also refer to the change in the direction of a wave when it meets an interface between two media.
- Therefore, when a wave such as light waves meets an opaque surface, they will bounce back off the surface.
- <em><u>The reflection of waves obeys the Laws of reflection such that the angle of reflection is equal to the angle of incident wave.</u></em>
