Answer:
38.1 N
Explanation:
The electrostatic force between two charged objects is given by:
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the two objects
In this problem, we have
so, the electrostatic force is
Answer:
Option B. 1,100 Earth diameters
Solution:
Angular position of steroid, (given)
To calculate the distance of asteroid, we use parallax method given as:
(1)
where,
From the relation:
l =
we get:
distance(d) or R =
distance(d) or R =
d =
distance, d =
Comparing it with Earth's diameter:
d =
Since, the value is close to 1,100 Earth diameters, therefore, option B is the right answer.
Low frequency, low amplitude, or both.
