Part a = the distance between the positive charge and the electron the charge on the electron the charge of the positive charge part b = the distance between the positive charge and the electron the charge of the positive charge part c = 6220 n/c click to use the calculator/solver for this part of the problem part d = g part e = 9.95 * 10-16 n click to use the calculator/solver for this part of the problem part f = c there is a single electron at a distance from the point charge. on which of the following quantities does the force on the electron depend? for the same situation as in part a, on which of the following quantities does the electric field at the electron’s position depend? if the total positive charge is q = 1.62*10−6 c, what is the magnitude of the electric field caused by this charge at point p, a distance d = 1.53 m from the charge? what is the direction of the electric field at point p? now find the magnitude of the force on an electron placed at point p. recall that the charge on an electron has magnitude e = 1.60 * 10-19 c. what is the direction of the force on an electron placed at point p?

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.

Dinate system, and a charge q = - 2.00 nc is placed s2 10 n> c. (a) what is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to es from parallel to perpendicular? (b) at what absolute temperature t is the average translational kinetic energy 32 kt of a molecule equal to the change in potential energy calculated in part(: abovethistemperature,thermalagitationprevents the dipoles from aligning with the electric field.) placed in a uniform electric field e with magnitude 1.6 * 6 on the positive x-axis at x = 4.00 cm. (a) if a third charge q3 = +6.00 nc is now placed at the point x = 4.00 cm, y = 3.00 cm, find the x- and y-components of the total force exerted on this charge by the other two. (b) find the magnitude and direction of figure p21.62 ll uu 21.55 . torque on a dipole. an electric dipole with dipole moment ps is in a uniform external electric field es. (a) find the orientations of the dipole for which the torque on the dipole is zero. (b) which of the orientations in part (a) is stable, and which is unstable? (hint: consider a small rotation away from the equi- librium position and see what happens.) (c) show that for the stable orientation in part (b), the dipole’s own electric field tends to oppose the external field. 21.62 ..
