Question

Two point charges Q1 = Q2 = +1.3 μC are fixed symmetrically on the x-axis at x = ±0.386 m. A point particle of charge Q3 = +4.4 μC and mass m = 18 mg can move freely along the y-axis.If the particle on the y-axis is released from rest at y1 = 0.019 m, what will be its speed, in meters per second, when it reaches y2 = 0.068 m? Consider electric forces only. v =

Answer #1

Use equation of work energy theorem to find the required speed of the charge at the final position as shown below

Two point charges Q1 = Q2 = +1.6 µC are
fixed symmetrically on the x-axis at x= ±0.147m. A point particle
of charge Q3 = +4.2 µC and mass m= 12 mg can move freely
along the y-axis.
(a) If the particle on the y-axis is released from rest at
y1 = 0.025 m, what will be its speed, in meters per
second, when it reaches y2 = 0.066 m? Consider electric
forces ONLY!

Two charges Q1 = -3 μC and Q2 = +3 μC are
located on the y-axis at y1 = -5 cm and y2 =
+5 cm respectively. A third charge Q3 is added on the
y-axis at y3 = -10 cm so that the electric field at the
origin is equal to zero. What is the charge Q3?

Three point charges are located on the x-axis at the
following positions: Q1 = +4.00 μC is at x = 1.00

μC is at x = -1.00 m. What is the magnitude of the
electric force on Q2? (k = 1/4πε0 = 8.99 × 109 N
∙ m2/C2)

Two point charges Q1 = 30.0 nC and Q2 =
-40 nC are held fixed along the x-axis. Q1 is at x = 0
and Q2 is at x = 72.0 cm. A third particle, of mass m =
2.2 x 10-6 kg, has charge Q3 = 42µC. If
Q3 is released from x = 28 cm, what is its initial
acceleration?
