Two concentric conducting spherical shells each have a net charge of 1 C and all charges remain at rest. The charge on the outer surface of the outer shell is 1 C. The outer surface of the outer shell is at a potential of 2 V. The inner surface of the inner shell is at a potential of V.

Ithink it is letter b, i may be wrong but i think that is the answer

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached
