In the figure, the point charges are located at the corners of an equilateral triangle 26 cm on a side. a)Find the magnitude of the electric field, in newtons per coulomb, at the center of the triangular configuration of charges, given that qa = 1.1 nC , qb = -5.9 nC , and qc = 1.5 nC.  b)Find the direction of the electric field in degrees below the right-pointing horizontal (the positive x-axis).

Imagine you have four identical charge q, placed on the corners of a square. If q = 17.37 nC, then the side of the square is s = 7.2 cm, calculate the magnitude of the electric field acting on the charge at the upper right corner. NOTE: Final answer in SIX decimal places. Then, state the SI unit of the variable being sought off. Add your answer

Two point charges are placed on the x-axis, +5.00 μC at the origin and -10.0 μC at x = 10.0 cm. (a) Find the electric field (magnitude and direction) on the x-axis at x = 6.00 cm.(b) : Draw a diagram and label the electric field vectors, including the net field vector, at point x = 6.00 cm. (Do not submit anything for part (b) on MasteringPhysics.)(c) Find the potential at x = 6.00 cm.  k = 9.0 × 109 N ∙ m2/C2

Two charges are located on an x-axis (as shown in the figure). One charge is located at the origin (q, = 0.40 µC). The other charge (92= -0.20 μC) is located at x-a, where a = 2.0 m. Calculate the x- and y-components of the electric field at a point P on the y-axis located at y= 2.0 m. From these components calculate the electric field magnitude and its angle with respect to the +x-axis (with angles increasing going counter-clockwise from +x, such that 90° corresponds to the y-axis). Ex = Ey = II Angle = N/C N/C N/C degrees P 91 a 92 X

A long silver rod of radius 3.0 cm has a charge of 5 microcoulombs per meter on its surface. Find the magnitude of the electric field at a point 5.0 cm from the center of the rod (an outside point). Round to 2 significant figures. what is the electric field at a point 2 cm from the central axis of the rod

(a) Determine the electric field strength at a point 1.00 cm to the left of the middle charge shown in the figure below. (Enter the magnitude of the electric field only.) Three charges lie along a horizontal line. A 6.00 µC positive charge is on the left. 3.00 cm to its right is a 1.50 µC positive charge. 2.00 cm to the right of the 1.50 µC charge is a −2.00 µC charge.  N/C(b) If a charge of −2.10 µC is placed at this point, what are the magnitude and direction of the force on it? magnitude      N direction
