Two charges are located on a horizontal axis. Determine the electric field at p on a vertical axis as shown in the figure, where up is positive. The Coulomb constant is 8.98755 Times 109 N m2 / C2. Answer in units of V/m Find the vertical component of the electric force on a -3.8 mu C charge placed at point p. Answer in units of N Two charges are located in the (x, y) plane as shown. The fields produced by these charges are observed at a point p with coordinates (0, 0). Find the x-component of the electric field at. p. The value of t he Coulomb constant is 8.98755 Times 109 N m2 / C2. Answer in units of N/ C In 1909 Robert Millikan was the first to find the charge of an electron in his now-famous oil drop experiment. In the experiment tiny oil drops are sprayed into a uniform electric field between a horizontal pair of oppositely charged plates. The drops are observed with a magnifying eyepiece, and the electric field is adjusted so that the upward force q E on some negatively charged oil drops is just sufficient to balance the downward force m g of gravity. Millikan accurately measured the charges on many oil drops and found the values to be whole-number multiples of 1.6 Times 10-19 C - the charge of the electron. For this he won the Nobel Prize. If a drop of mass 2.44898 Times 10-13 kg remains stationary in an electric field of 1 Times 106 N/C, what is the charge on this drop? The acceleration due to gravity is 9.8 m/s2 . Answer in units of C How many extra electrons are on this particular oil drop (given the presently known charge of the electron)? Three positive charges are arranged as shown at the corners of a rectangle. Find the magnitude of the electric field at the fourth corner of the rectangle. The value of the Coulomb constant is 8.98755 times 109 N m2/C2. Answer in units of N/C What is the direction of this electric field (as an angle measured from the positive x-axis, within limits of -180 degree to 180 degree, with counterclockwise positive)?
