Question
Please help!! Thank you Student's name Gioias Delig 01n ordinary laboratory circuits, charges in the AcC and nC range are common. How many excess electrons must you add to an object to give it a charge of (a)-250 C, (b)-250C . If a proton and an electron are released when they ane 80 20 x 10-10 m apart (typical atomic distances), find the initial acceleration of each of them. . Two point charges are placed on the x axis as follows Charge q+4.00 nC is located at -0.200 m, and charge -+500 nC isatx-0.300 m. What are the mag and direction of the net force exerted by these two charges on a negative point charge =-0.600 nC placed the origin? 30 tude A small object carrying a charge of -8.00 nC is acted upon by a downward force of 20.0 nN when placed at a certain point 2o in an electric field. (a) What are the magnitude and direction of the electric field at the point in question? (b) What would be the magnitude and direction of the force acting on a proton placed at this same point in the electric field? The electric field caused by a certain point charge has a mag- 0 nitude of 650x10' N/C at a distance of 0100 m from the charge. What is the magnitude of the charge?Explanation / Answer
10] q = ne
e = - 1.6 x 10-19 C
a] - 2.5 x 10-6 = ne
n = 1.5625 x 1013
b] - 2.5 x 10-9 = ne
n = 1.5625 x 1010 .
these are the number of excess electrons to be added to the object.
