Answer:
Astronomers use a method similar to the one you used with your homemade quadrant. Twice the distance to the Sun, divided by the distance to the star (which is unknown so far) is equal to the tangent of the parallax angle of the star.
Answer:
.
Explanation:
Since no external force is acting on the system.
Therefore, Total energy remains constant before and after.
So, Total energy of system= energy due to potential applied+kinetic energy
(Here v=velocity ,V=potential ,q=charge and m=mass).
Putting values .
We get, .
At point B charged particle is moving faster as compared to point A.
Hence, it is the required solution.

Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. ... For example, a book resting on a table applies a downward force equal to its weight on the table.
