An insulating hollow sphere has inner radius a and outer radius
b. within the insulating material the volume charge density is given by r1r2 = a/r, where a is a positive constant. (a) in terms of a and a, what is the magnitude of the electric field ,wherea6r6b? (b) a point charge q is placed at the center of the hollow space, atr = 0.intermsofaanda, whatvaluemustqhave(signand magnitude) in order for the electric field to be constant in the region a 6 r 6 b, and what then is the value of the constant field in this region?

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
