<h2>Answer:</h2>
If you triple the charge, the electric potential is 3V.
<h2>Explanation:</h2>If you triple the charge, the electric potential is 3V. Put another way, the value of the electric potential at the same location is tripled if the strength of the charge is tripled.
<em>But why this is true?</em>
Well, the potential V due to a single point charge q is:
If the strength of the charge is tripled means that our new q1=3q, therefore:
So you can see that in fact if you triple the charge, the electric potential is 3V.
Answer:
x = 1.63 m
Explanation:
mass (m) = 10 kg
μk = 0.3
velocity (v) = 3.1 m/s
Assuming that most of the computers weight is applied on the belt instantaneously, we can apply the constant acceleration equation below
x =
where a = μk.g , therefore
x = /2μk.g
x = (3.1 x 3.1)/(2 x 0.3 x 9.8)
x = 1.63 m
