Help me Guys ! i need the answer of this 3 question :(
Guys ?? i really need the answer of this 3 questions .. I don't know how to answer this one .. help me guys ..
1.) Compute the electric force acting between the electron and the proton in a hydrogen atom. The radius of the electron's orbit around the proton is about 5.3x10^(-11) m.
2.) The current that flows through an incandescent light bulb immediately after it is turned on is higher than the current that flows moment later. Why?
3.) A permanent magnet is made of a ferromagnetic material with a magnetization M of about 8x10^5 A/m. The magnet is in the shape of a cube of side 2 cm.
a.) Find the magnetic dipole moment of the magnet.
b.) Estimate the magnetic field due to the magnet at a point 10 cm from the magnet along its axis.
NOTES:
1.) 5.3x10^(-11) is "5.3 times 10 raised to the exponent -11".
8x10^5 is "8 times 10 raised to the exponent 5".
2.) Problem #3 is a sample problem in University Physics by Young & Freedman (11th or 12th edition) so provide the necessary details.

Thanks In advance
