I Ulll'lll EIUUIEIIIO Three very small, charged spheres, each with mass 4.0)(104 g, are placed u - ' II .I' at the corners of a triangle (see figure). The charges are +7.0 uC, -8.0 uC, 3: l and -6.0 uC, and the distance between each charge is 1.20m. Calculate 3:." if the magnitude and direction of the net electric field at the location of Q, 5:" c?- and use your answer to calculate the force on q. Compare your answer \\' to your calculation from last week's turn-in problem 'I. 4 ' __ [a __b:.,_-( 1:)._hl E\"- Consider the setup and your calculation from problem 'I. If q is now tripled in charge, and is negatively-charged instead of positively-charged, use the electric field you determined in problem 1 to calculate the magnitude and direction of the net electric force on it due to the other two charges (which have not changed}
