Apoint charge is located at (d, 0, 0) from the intersection of two grounded conducting planes with y = 0 and z = 0. if we consider the region z> () and x = 0, the leading order behavior of the potential for r > > d is proportional to, a. d2/r4 sin(o)cos(0) b. d/r2 c. d4/ro cos2(0) d. d2/r3 sin(o)cos(0)

B) raising the temperature and reducing the volume of the gas.|-/ 

The best answer is (a) which is universal law is in effect at all times. it is constantly at play in everything we do and governs our lives. it is also important to note that universal law applies to not only everything on earth, but everything in the universe as well, which is another reason why it is in effect at all times.

Ke reqd to move from 0 to 50 will be proportional to 50x50 or 2500. this is equal to w.  to change vel from 50 to 150 you need energy prop to 22500 - 2500 = 20,000. this corresponds to 8w.  best answer is a) . work reqd is prop to velocity squared.
