Activity 2 1. Problem Solving: Direction. Read each problem carefully, show your solution and write the answer on your answer sheets. 1. Calculate the electric flux, & for each of the closed surfaces 1, 2, 3 and 4. Where q1 = -8C, q2 = +2C, q3= +3C, q4= +4C, q5= +6C, q6=+7C, q7 = -4C, and q8 = 5C. 2 3 2. Calculate the magnitude and direction of the electric field 1.5 meter from a +9.64 x 10"C point charge. 3. A small ball weighing 0.0085 kg with a charge of +4.5 x 10-C. What electric 97 95 field is needed to make the small ball remain suspended in air? 4. Two-point charges q1 = 6.5 x10-6C and q2 = -6.5 x10-C are separated by 98 96 7.6 x 10-2meter forming an electric dipole shown. Calculate the electric field halfway between the dipoles. 5. Calculate the electric flux through the top, bottom, right and left sides of the cube. The side of the cube is 0.5m when placed in a horizontal uniform electric field of 7 N/C directed to the right
