Calculate the magnitude of the electric field at one corner of a square 1.52 m on a side if the other three corners are occupied by 3.75x10-6 C charges. Express your answer to three significant figures and include the appropriate units. E = Part B μA Submit Request Answer Value Ο Ο Ο Ο Units ? What is the direction of the electric field at the corner? along the line between the corner and the center of the square toward the center O along the line between the corner and the center of the square outward of the center along the side of the square between the corner and one of the charges toward the charge along the side of the square between the corner and one of the charges outward of the charge

Protons are projected with an initial speed v. = 9,950 m/s into a region where a uniform electric field of magnitude E = 540 N/C is present (see figure below). The protons are to hit a target that lies a horizontal distance of %3D 1.30 mm from the point where the protons are launched. Target -R Proton beam (a) Find the two projection angles 0 that will result in a hit. (Enter the smaller angle first.) 02 = (b) Find the total duration of flight for each of the two trajectories. (Enter the smaller duration of flight first.) t = t2 = %3D IL || I|||

Determine the magnitude of the electric field at any point P a distance x from a very long line (a wire, say) of uniformly distributed charge. Assume x is much smaller than the length of the wire L, and let A be the charge per unit length (C/m). Z

A-1.5-μC charge experiences a 10î -N electric force in a certain electric field. Part A What force would a proton experience in the same field? Express your answer in newtons. ΠΠ ΑΣΦ Fx = ? N

Determine the magnitude of the acceleration experienced by an electron in an electric field of 526 N/C. Express your answer to three significant figures and include the appropriate units. μA Value Submit Request Answer BE Units ?

In Configuration 1 below, what is the magnitude of the predicted electric field at point b? Point b is 2.00 m from the +3.00 nC charge (this is also in your lab procedure). Pt. a Pt. b Pt. c +3 nC figure 1 a Your answer should: Be in the Correct SI Units of N/C Be rounded to 2 Decimal Places For this problem you can't enter a number in Scientific Notation (the program doesn't allow it). For example: 2.06 x 102 would be written as 206.00

ST At a distance of 48.7 cm from a very long (essentially infinite) uniform line of charge, the electric field strength is 1,866 N/C. At what distance (in cm) from the line will the field strength be equal to 811 N/C? X
