Question
A +4.0 mu C point charge is placed at the center of a cube. The electric flux through a pair of sides of the cube is: 4.5 times 10^5 N middot m^2/C 1.5 times 10^5 N middot m^2/C 7.5 times 10^4 N middot m^2/C 450 N middot m^2/C Can you add additional charge to a spherical conductor just by approaching (not touching) a charged rod near the conductor? Yes No Depends on the material of the conductor A section of a cone is shown in the diagram such that the section has a curved part and both a tint top and bottom. The shape is a Gaussian shape surrounding a collection of charges that produce a flux through the curved surface of + 2.3 times 10^6 N middot m^2/C and through the flat base plus top of + 9.8 times 10^5 N middot m^2/C. What is the total charge inside the Gaussian shape? 29 mu C 20 mu C 12 mu C 8.7 mu C 0.029 mu C A spherical conducting shell has total charge of +6 C. A point charge of -8 C is placed at the center of the cavity inside the shell. The charge on the inner surface of the shell and the charge on the outer surface of the shell, respectively, are: -8 C, 0 +8 C, -2 C 0, -2C +8 C, +14 C Two point charges, -20.0 nC and +5.00 nC, are separated by 4.00 m as shown. What is the electric potential 2.00 m to the left of the +5.00 nC charge? 52.4 V -30.0 V 22.5 V -7.50 V -6.24 V A total charge of -7.0 nC is uniformly distributed throughout a non-conducting sphere with a radius of 5.0 cm. The electric potential at the surface, relative to the potential far away is about: +1.3 kVExplanation / Answer
Q. 11 ( yes)-
Q. 13 ( option B , +8 , -2)
Q. 14 (V = 9 x 10^ 9 [ 5 x10^-9/ 2 - 20x 10^-9/ 6) = 9 ( 2.5 - 3.33) = -7.5 (correct option isD)
Q. 15 V = 9 x 10^9 ( -7 x 10^-9)/ ( 5 x10^-2) = -12.6 x 10^2 V apprx
