An electron is initially moving to the right when it enters a uniforn electric field directed upwards. Which trijectory will the electron flow

A point charge q= 4.7 uC is placed at each corner of an equilateral triangle with sides 210mm in length. (a) What is the magnitude of the electric field at the midpoint of any of the three sides of the triangle? b) is the magnitude of the elctric field at the ceneter of the triangle less than, greater than or the same as the magnitufr at midpoint of a side? Draw a skwtch with all apprpoate vectors.

An electric dipole consists of two charges, +4 μC and -4 μC, separated by a distance of 2 cm. Determine the electric field strength at a point on the axial line of the dipole, 4 cm away from its center.

What must the charge (sign and magnitude) of a 2.45 g particle be for it to remain stationary when placed in a downward-directed electric field of magnitude 650 N/C ? Express your answer in microcoulombs.

(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.) (b) If a charge of −6.49 µC is placed at this point, what are the magnitude and direction of the force on it?
