A metal sphere with radius ra = 1.20cm is supported on an insulating stand at the center of a hollow, metal, spherical shell with radius rb = 9.90cm . Charge +q is put on the inner sphere and charge ?q on the outer spherical shell. The magnitude of qis chosen to make the potential difference between the spheres 500V , with the inner sphere at higher potential.

Part A
Calculate q.
q = C
Part B
Are the electric field lines and equipotential surfaces mutually perpendicular?
Yes
No
Part C
Are the equipotential surfaces closer together when the magnitude of E? is largest?
Equipotential surfaces closer together when the magnitude of E? is largest.
Equipotential surfaces closer together when the magnitude of E? is smallest.

Which situation will produce the greatest change of momentum

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
