Answer:
decrease by a factor 10
Explanation:
The parallax angle of a close star is given by
where
p is the parallax angle
d is the distance of the star from Earth, in parsecs
From the formula we see that the parallax angle is inversely proportional to the distance.
In this problem, the distance of the star is increased by a factor 10:
d' = 10 d
so the new parallax angle would be
So, the parallax angle would decrease by a factor 10.
Answer:
(a) Both the charges are positive or negative.
(b) Teh value of each charge is 1.53 x 10^-5 C.
Explanation:
Spring constant, K = 340 N/m
Natural length, L = 0.4 m
stretch, y = 0.033 m
(a) Let the charge on each sphere is q and they repel each other so the nature of charge of either sphere may be both positive or both negative.
(b) The electrostatic force is balanced by the spring force.
