Two d = 4.40-m nonconducting wires meet at a right angle. One segment carries +2.90 μC of charge distributed uniformly along its length, and the other carries -2.9 µC distributed uniformly along it, as shown in the following figure. K d d ++++ P (a) Find the magnitude and direction of the electric field these wires produce at point P, which is 220.0 cm from each wire. (Assume the +x axis goes to the right.) magnitude direction N/C 。 counterclockwise from the +x direction (b) If an electron is released at P, what are the magnitude and direction of the net force that these wires exert on it? magnitude N direction ° counterclockwise from the +x direction

Inside a cathode ray tube, an electron is in the presence of a uniform electric field with a magnitude of 275 N/C.

In the figure shown, q = 1.00 C. (a) What is the electric field's magnitude at x = 5.00 cm. (b) Find the location between the left side +q and the -2q charge where the field's magnitude is equivalent to that sourced individually by the -2g charge. (c) Does the electric field vanish at any position (other than negative infinity) left of the -2q charge? (d) The electric field vanishes for positions far to the left or right of the charges shown. Along which direction does the field's magnitude vanish more quickly? Elaborate. x (cm) -2q 10 +q +q

In this experiment oil drops are suspended in a vertical electric field against the gravitational force to measure their charge. If the mass of a negatively charged drop suspended in an electric field of 1.76 ✕ 10−4 N/C strength is 2.299 ✕ 10−20 g, find the number of excess electrons in the drop.

Five equal negative charges are uniformly spaced in a semicircular arc of radius ro with its center at the origin. The charges positions in polar coordinates are given by ( ro, θi ), where the values of θi are 0°, 45°, 90°, 135°, and 180°. At the position ( x, y ) = ( ro, −ro ) in the 4th quadrant, which statement best describes the direction of the resulting electric field? Group of answer choices The direction is that of a 2nd quadrant angle. The direction is that of a 4th quadrant angle. The direction is that of a 1st quadrant angle. The direction is that of a 3rd quadrant angle.
