Answer:
Explanation:
According to Newton's law of universal gravitation:
Where:
is the module of the force exerted between both bodies
is the universal gravitation constant.
and
are the masses of both bodies.
is the distance between both bodies
In this case we have two situations:
1) Two bags with masses and
mutually exerting a gravitational attraction
on each other:
(1)
(2)
(3)
2) Two bags with masses and
mutually exerting a gravitational attraction
on each other (assuming the distance between both bags is the same as situation 1):
(4)
(5)
(6)
Now, if we isolate
from (3):
(7)
Substituting found in (7) in (6):
(8)
(9)
Simplifying, we finally get the expression for in terms of
:
Answer:
a)
b)
Explanation:
Given:
charge at the origin,
a)
Electric field at point :
The distance form the charge:
Now the electric field at the given point:
b)
Electric field at point :
The distance form the charge:
Now the electric field at the given point:
