Answer:
Given: V=12 V
I=2.5 mA
Let the resistance be R
By Ohm's Law,
V=IR
12=2.5×10−3R
R=4.8×103 Ω
The Gravitational Force is reduced 4 times
Explanation:
The equation of Gravitational force follows:
F = (G*m1*m2)/r^2
Assume that G*m1*m2 = 1 and r = 1:
F = 1/1^2 = 1 N
Multiply the radius by 2
F = 1/2^2 = 1/4 N
So doubling the distance reduces the force 4 times.
