As shown in the figure, a proton is at the origin and an unknown charge is at x = +4.0 nm. If the net electric force on a small positive test charge is zero at x = -3 nm, what is the magnitude and sign of the unknown charge? test charge q unknown charge Q proton x=-3 nm x=0 x=+4 nm 0 +0.19e 0 -0.19e 0 +5.4e 0 -5.4e 0 -2.7e
The figure shows two electrons separated by a distant d. Point P is a distance d/4 from the rightmost charge. If d is equal to 3 nm, what is the magnitude of the net electric field at point P, and which way does it point? electron Р electron d/4 d 1.1E9 N/C, to the right 01.1E9 N/C, to the left 2.3E9 N/C, to the right O 2.3E9 N/C, to the left 4.4E9 N/C, to the right
A spark is generated in an automobile spark plug when there is an electric potential of 3000 V across the electrode gap. If it takes 100 ns for the spark to jump across the gap and the total charge that travels across the gap is 2.5 nC, what is the power generated by a single spark? O 10W 0 25 W 40 W O 60W O 75W Question 4 5 pts A green laser operating at 532 nm shines light onto two-closely spaced slits. An interference pattern is created on a distant screen. If the fifth dark fringe appears on the screen at an angle of 0.12 degrees with respect to the center line, what is the slit separation distance? O 1.85 mm 01.10 mm O 5.55 mm O 11.1 mm 0 4.62 mm
