Question

Constants Two point charges q1 and q2 are held in place 4.50 cm apart. Another point charge Q-2.00 μC of mass m 4.50 g is initially located 3.00 cm from each of these charges (the figure(Figure 1)) and released from rest. You observe that the initial acceleration of point charge Q is a 324 m/s2 upward, parallel to the line connecting the two point charges. Part A Find qi and q2 Enter your answers numerically separated by a comma.

Answer #1

Part A

I f the acceleration of point char ge Qis upward, means that

1 s positve

g2 is negative

g1 and q2 have the ame charge i s

From Coulombs law

F_{AB}=krac{q_AQ_B}{r_{AB}^{2}}

Also, from Newtons second law, upward force is:

Fma (4.5 x 10-3 k3241.458 N

This is the force exerted bu a and gp. So, vertical force, should be:

F=2F_{up}

0.729 N Fup - 2

Force between Q and qi is

4.5 cmn cos α = 0.75 Fo. 3 cm

Q.qi = 0.972 N cos d

Using Coulombs law:

F_{Q,q_1}=krac{Qq_1}{r^{2}}=left ( 9 imes 10^{9} :rac{Nm^{2}}{C^{2}} ight )left [ rac{left | -2 imes 10^{-6}:C ight |q_1}{left ( 0.03 ight )^{2}} ight ]

substituting:F_{Q,q_1}:and:solving:for:q_1:

gi = 4.86 × 10-8 C

q_2:should:be:

g-=-4.86 × 10-8 C
