Answer:
the sun is larger in mass and therefore gravitational pull.
Explanation:
Fun fact the moon has more gravitational force on the earth than the sun because its closer to the earth.
Answer:
a)v= 675V
b) v=-675V
c)v=-450V
Explanation:
Formula: V = k*sum(qi/ri)
Given:
q1 = +6.00nC --> R1 = 2.00cm
q2 = -9.00nC --> R2 = 4.00cm
(a) r = 0. So, inside both shells
V=675V
(b) r = 4.00cm. So, This point is outside of shell 1 but inside shell 2.
V=-675V
(c) r = 6.00cm. So, This point out of both shells.
In series circuit, Req = R₁ + R₂ + R₃ + ···
In parallel circuit,
<h3>Q7.</h3>
total resistance in the upper branch = R₂ + R₃ = R₂ + 2
R₂ + 2 = 12
R₂ = 10Ω
<h3>Q8.</h3>
Req = 1.7Ω
