MY NOTES I I ASK YOUR TEACHER I ' PRACTICE ANOTHER The radius of a solid conducting sphere is R = 14.0 cm and it has a uniformly distributed charge of 30.5 nC on its surface. The center of the sphere is at the origin of the xy coordinate system. The locations A, B, and C are at (-R/3, 0) cm, (-R, 0) cm, and (3R, 0) cm, respectively. Determine the potential difference v, - V and V - V.. Note that the diagram is not to scale. Additional Materials [ Reading Submit Answer 10. [-/2 Points] DETAILS OSUNIPHYS1 24.5.P.059. MY NOTES I | ASK YOUR TEACHER I ' PRACTICE ANOTHER A very large sheet of insulating material has had electrons removed from it to yield a surface charge density of +9.00 nC/m2. (a) As the distance from the sheet increases, does the potential increase or decrease? O increase O decrease Can you explain why without any calculations? O The electric field points in the direction of decreasing potential while pointing towards negative charges and away from positive charges. ) The electric field points in the direction of decreasing potential while peinting away from negative charges and towards positive charges. ) The electric field points in the direction of increasing potential while pointing towards negative charges and away from positive charges. ) The electric field points in the direction of increasing potential while pointing away from negative charges and towards positive charges. Does the location of your reference paint matter? O Yes O No (b) What is the shape of the equipotential surfaces? O planes perpendicular to the sheet O spheres whose centers do not lie on the sheet @ spheres whose centers lie on the sheet O planes parallel to the sheet (c) What is the spacing (in m) between surfaces that differ by 7.00 V? m
