Question

10) Electrons will low freely through which of the following A) copper 8) sulfur plasticD) rubber 11) An object that is negatively charged: A) has gained protons C) has gained electrons B) has lost protons D) has lost electrons 12) An electric field is to be measured using a positive test charge of 3 0 x 10-5c is test charge experiences a force of 0 50 N acting at an angle of 15 degrees What is the magnitude of the electric field at the location of the test charge? (HINT: use E = F/ ) A) 1-7 x 10 NIC 8) 0 49 Nr C) 1-7 x 10 N/C D)6.0x 10s NC 13) An obiect that is positively charged

Explanation / Answer

10) copper is a conductor which allows the allows the electrons.

11) negativels charged object has excess number of electrons

12) f = Eq

E = f/q = 0.5/3*10^-5 = 1.7*10^4 N/c
