Its A The paper clip is repelled away from the nail because an electromagnetic field magnetized to the nail
Technically, we don't have the information needed to calculate the current,
because you haven't mentioned the units of the 3.5 .
Since the 3.5 is a resistance, we strongly suspect ... and we'll therefore
assume ... that the 3.5 has the units of ohms. Then . . .
Current = (voltage) / (resistance) = (1.5/3.5) = <em>3/7 of an Ampere</em>.
(429 mA, rounded)
Like charges repel, while opposite charges attract.
The answer is 3) 3.00 m/s2
