The electric field strength is
Explanation:
The strength of the electric field produced by a single point charge is given by:
where
is the Coulomb's constant
q is the magnitude of the charge
r is the distance from the charge at which the field strength is calculated
For the charge in the problem, we have:
is the charge
Therefore, the electric field strength is

Answer:
<u>Option-(A): </u>A new moon is quite near the Sun in the sky.
Explanation:
- While the position of the new moon inside our sky has such an orientation that we are not able to see or observe the actual position and shape of the new moon.
- As the path or revolution is much more elliptical then we can imagine, for the moon there are certain position of motion inside the celestial space that for some times it looks for different then the other and such position generates the concept of a new moon.
