Question 9 only

[9] #9. The electric potential in a region of space is given by V = (-1.0 V/m2)x2 + (3.0 V/m?)y-(2.0 V/m)z'. Determine the electric field in the form E = Exi + E,j + Eck at the point (-1.0 m, +3.0 m, -2.0 m)_ Answers: a E= (5.0 V/m)i+ (-12.0 V/m)j +(-15 V/m)k b. E= (3.0 V/m)i + (24.0 V/m)j - (0 V/m)k C. E= (-2.0 V/m)i+ (-3.0 V/m)j + (24 V/m)k d. E= (-8.0 V/m)i + (-18 V/m)j + (20 V/m)k e. E= (-6.0 V/m)i + (-30 V/m)j + (-5.0 V/m)k . Give your answer in the form "x". [6] #10. At a certain location the electric field is given by E = (-3.8 i - 1.2 j + 5.1 k) V/m. Determine the electric flux through a surface whose area vector at that location is A = -15.8 (m) k. Give your answer in the form "abc x 10^(x)" N/C.m2 [9]#11. The sketch at the right shows some lines representing a section of an electric field.
