What electric field would produce a 10 N force in the +x direction on a charge of-10 nC?

What are the magnitude and direction of an electric field that exerts a 1.45 x 10^-5 N upward force on a -2.60 uC charge?

S. The pith ball shown below has a mass of I gram and a charge of-3nC. When an electric field, E, is tumed on the pih ball moves into equilibrium as shown below. The tension in the string is 10mN at 30 to the horizontal. mi gm T 10mN Find the magnitude and the direction of the E field a. JE-5.710 NC @ 60 deg 3rd Quadrant (240 deg) b. JE-33*10 NC @ 30 deg 3rd Quadrant (210 deg) c. JE-5.7*10 NC @ 30 deg Ist Quadrant (30 deg) d. JE-33*10 N/C @ 60 deg Ist Quadrant (60 deg)

If the earth's electric field is 820 N/C downward, what must be the charge on a 8.0-kg object so that it would be "weightless"?

An electric field of magnitude 5.25 x 10° N/C points due east at a certain location. Find the magnitude and direction of the force on a-4.25 µC charge at this location. N |---Select-- v magnitude direction
