Step 1 of 3

9/22/16 Physics 133—Dr. Srinivasan 4 Fundamental Forces: 1) Strong a. The force -15t holds the nucleus together b. Range: 10 m, the diameter of a medium sized nucleus 2) Electromagnetic 1 a. Strength: of the strong force 137 b. Fundamental property: charge c. Range: infinite d. Repulsion is the surest test for electrical interaction 3) Weak a. Occurs in neutrino interaction b. Range: 10 , 0.1% the diameter of a proton 1 -6 c. Strength: 1,000,000 (10 ) of the strong force 4) Gravity a. Strength: 6 x 10-3of the strong force b. Range: infinite Charge  A property of matter (Units−19oulomb)  It is quantized-- |e=1.6×10 C  Only two kinds of charges are known to us (positive and negative)  Electrons are the primary charge carriers o Flow of electrons makes up an electrical current  Charge can be transferred  Law of Conservation of Charge: o Charge is a conserved quantity; the amount of charge in a closed system is constant o Charge cannot be created or destroyed  Closednon-interacting  Charges interact by exerting forces on each other  Charging—generating a region of excess charge o Charging by contactconduction o Charging w/o contact (no physical transfer)induction
