Electric load holds onto electricity
Power source shoots electricity out
Conductors allow electricity to pass through
Let e be the charge of the electron.
Then F1 + F2 = 0
F1 = K (-1.5) * (-e) /r1^2
F2 = K (15) * (-e) /r2^2
(-1.5) * /r1^2 + (15) /r2^2 = 0
-1 /r1^2 + (10) /r2^2 = 0
[r2/r1]^2 = 10
[R2/r1] = ± 3.162
r2 = ± 3.162 r1.
Given r1 + r2 = √ [1^2 + 0.5^2] = 1.1180-----1
Also tan θ = 0.5 => θ = 26.57°
====================================
Substituting r2 = 3.162 r1 in 1
4.162 r1=1.1180
r1 = 0.2686 m
x coordinate = r1 cos θ = 0.2403 m
y coordinate = r1 sin θ = 0.1201m
===================================
Substituting r2 = - 3.162 r1 in 1
-2.162 r1=1.1180
r1 = -0.5171m
x coordinate = r1 cos θ = -0.4625m
y coordinate = r1 sin θ = -0.2313m
===============================
The magnitude of the E-field decreases as the square of the distance from the charge, just like gravity.
Location ' x ' is √(2² + 3²) = √13 m from the charge.
Location ' y ' is √ [ (-3)² + (-2)² ] = √13 m from the charge.
The magnitude of the E-field is the same at both locations.
The direction is also the same at both locations ... it points toward the origin.
Answer: What happens when the thermal energy of a substance increases is that D. Both the motion of the particles in the substance and the temperature of the substance increase.
Explanation: When thermal energy increases, it is due to particles moving faster. It also results in higher temperatures or heat.
