Which of the field patterns given in the figure is valid for electric field as well as for magnetic field?

Options

Correct answer

C. What is the edge length of a unit cell in a cubic close-packed (ccp) structure in terms of the sphere radius (r)?

Step-by-step solution

Correct answer is (c), because induced electric field lines (produced by change in magnetic field) and magnetic field lines form closed loops. Analysis of Question Question is simple, provided you have an idea of induced electric field lines.
