Two point charges, q1 = μC and q2 = μC, are placed on the corners of a rectangle as shown in the figure, where h = m and w = m. The x component of the electric field due to q2 at the origin O is: Give your answer in units of N/C and round to the nearest whole number. Your answer should be numerical only, don’t type the units. Hint: Components of vectors can be positive or negative. For example, if a vector is pointing in the negative x direction, then the x-component should be negative. No partial credit for missing a negative sign.

Negative charge -Q is distributed uniformly along the x-axis between x=-d and x=+d. Which integral would give you the y-component of the electric field at point P with the correct sign (positive or negative)?  Question ID 3652755

Consider an insulating (non-conducting) sphere with radius b. It has a charge -Q uniformly distributed over its volume. What is the magnitude and direction of the electric field at a distance a from the center of the sphere if a > b? Question ID 3659974

Two point charges q1 =

Negative charge -Q is distributed uniformly along the x-axis between x=-d and x=+d. Which integral would give you the x-component of the electric field at point P with the correct sign (positive or negative)?  Question ID 3652774

Two point charges, q1 = μC and q2 = μC, are placed on the corners of a rectangle as shown in the figure, where h = m and w = m. The y-component of the total electric field at the origin O is: Give your answer in units of N/C and round to the nearest whole number. Your answer should be numerical only, don’t type the units. Hint: Components of vectors can be positive or negative. For example, if a vector is pointing in the negative y direction, then the y-component should be negative. No partial credit for missing a negative sign.

Of the three scenarios listed below, determine which has the greatest magnitude of current through the source and calculate that value.   A. a -Ω resistor connected to a 1.5-V battery that has an internal resistance of 0.10 Ω. B. an unknown resistor connected to a 13.0-V battery that has an internal resistance of Ω and a terminal voltage of 11.0 V. C. a -Ω resistor connected to a 4.0-V battery that has a terminal voltage of 3.6 V but an unknown internal resistance. Express your answer in units of A and to 2 decimal places. Numerical answer only. Don’t type in the units or use scientific notation.

Consider the charges below arranged on the vertices of an equilateral triangle. What is the direction of the net force on q2 if |q1|=|q2|=|q3|? Question ID: 3778895
