1. Determine which of the following statements are correct or incorrect. If a statement is incorrect, explain how you could change it slightly to fix it. Hint: Bob is the one who said all of the statements.

"Right now my cell phone is charged up with 5V of charge."

"Those strong neodymium magnets from lab pull on the weak bar magnets with a lot more force than the weak magnets pull on the strong magnets."

"It's impossible to use Ampere's Law inside a wire because there's no way to get an Amperian loop through the solid metal."

"That 2 meter long wire has an enormous voltage - the entire wire is at a constant 10,000V. There must be a huge electric field inside!"

Explanation / Answer

(1) Flase: Charge cant be measured in volt. Its unit is coulomb

(2) False: Force on both strong and weak bar magnetic is same. This can be explained from Newtons 3rd law

(3) Flase: Ampere law can be used inside the wire though the current inclosed might be less than total current in the wire

(4) False: Electric field inside the mettalic (conductor) wire is always zero.
