Question

13) What is the direction of the electric field in the area between the conductive cylinder and the shell? + O in the radial direction towards the outer shell 6)A ring with a radius a is uniformly distributed over the negative q charge in the xy-plane. In which direction is the electric field at the z = -a point on the z-axis? O negative x axis direction O negative y axis direction O positive x axis direction O it is zero, it has no direction. O parallel to the axis O in the radial direction towards the inner cylinder 14) What is the surface charge density o on the surface of the inner cylinder? O positive z axis direction O negative z axis direction O positive y axis direction O other: O 1/(417) O 1/(ar?) 01/(49r2) O 1/(2ar) OM/T O //(2011) Oo 7)A ring with a radius a is uniformly distributed over the negative q charge in the xy-plane. In which direction is the electric field in the center of the ring? O negative x axis direction O negative y axis direction O positive x axis direction O positive z axis direction O negative z axis direction O positive y axis direction O other: 8)The two quadrants with radii a are loaded properly with the opposite load and are combined as shown. What is the potential in the center of the circles? O Q/(2762) O Q/(Tea?) O Q/(41&pa) + O Q/(mega) Oo. other:

Answer 1

13) the answer is option (a)in the radial direction towards the outer shell. As the inner cylinder is having positive charge ant outer shell having negative so field travels from positive to negative.
