Identical 50 μC charges are fixed on an x axis at x = ±3.0 m. A particle of charge q = -15 μC is then released from rest at a point on the positive part of the y axis. Due to the symmetry of the situation, the particle moves along the y axis and has kinetic energy 1.2 J as it passes through the point x = 0, y = 4.0 m. (a) What is the kinetic energy of the particle as it passes through the origin? (b) At what negative value of y will the particle momentarily stop?

Question:

Identical 50 μC charges are fixed on an x axis at x = ±3.0 m. A particle of charge q = -15 μC is then released from rest at a point on the positive part of the y axis. Due to the symmetry of the situation, the particle moves along the y axis and has kinetic energy 1.2 J as it passes through the point x = 0, y = 4.0 m.
(a) What is the kinetic energy of the particle as it passes through the origin?
(b) At what negative value of y will the particle momentarily stop?

Answers

Answer:14 JExplanation:Let the angle of charge be θThen the distance from the x-axis = 3 mThe angle is given as [tex]tan (\theta) = \frac{3}{3}\\ \theta = tan^{-1} (1)\\ = 45[/tex]Similarly, the charge is on the left side, so the distance will be - 3 mThe angle therefore will be  = 45°So we need to find the net force given by the law:[tex]F = \frac{kq_{1}q_{2} }{r^{2} }[/tex]The distance between the points will be [tex]\sqrt{(3)^{2} +(3)^{2} }[/tex]= 3[tex]\sqrt{2}[/tex]
