Answer:
a)The sign of energy is negative, b) we can approach the two charges, c) d ⇒ 0
Explanation:
a) The elective potential energy is
U = k q₁q₂ / r
Applied to this case.
U = -k q 9 / d
U = -9 k q / d
The sign of energy is negative, which corresponds to a stable system
b) c) for the energy to be more negative we can approach the two charges
c) To increase the energetic of the system, that is to say less negative, we can separate the discharges whereby U approaches zero or we can decrease the value of the charge q.
d ⇒ 0
The convex mirror form an image by bouncing the light away from a focal point.
Answer: Option D
<u>Explanation:
</u>
A diverging mirror is a reflecting surface which is a spherical one. The bulging side of the convex mirror will face towards the light source. It is a diverging mirror in which rays diverge upon after reflection. These are often used in the mirrors that are in the automobiles.
The image that is formed by the convex mirror cannot be displayed on the screen. Hence, they are called as Virtual image. The resulting image by the convex mirror is upright, virtual and size diminished.
