Answer:
option E
Explanation:
given,
Parallax angle(d) = 1 arcsecond
using Parallax formula
p is the parsecs angle which is measured in 1 arcsecond
d is the distance in parsec
now,
we know,
1 parsec = 3.26 light year
hence, the answer will be option E
We have that the electric field at the center of the metal ball due only to the charges on the surface of the metal ball is
From the question we are told that
A solid metal ball of radius 1.5 cm
bearing a charge of -15 nC is located near a hollow plastic ball of radius 1.9 cm bearing
uniformly distributed charge of -7 nC
The distance between the centers of the balls is 9 cm
Generally the equation for the electric field is mathematically given as
