Question
Points A, B,and C are at the corners of an equilateraltriangle of side 3.00 m. Equalpositive charges of 5.00 µC areat A andB. (a) What is the potential atpoint C? (b) How much work is required tobring a positive charge of 5.00 µC from infinity topoint C if the other charges are heldfixed? (c) How much additional work isrequired to move the +5.00 µC point particle frompoint C to the midpoint ofsideAB? (a) What is the potential atpoint C? (b) How much work is required tobring a positive charge of 5.00 µC from infinity topoint C if the other charges are heldfixed? (c) How much additional work isrequired to move the +5.00 µC point particle frompoint C to the midpoint ofsideAB?Explanation / Answer
(a) What is the potential atpoint C?potential=9*109*5*10-6[1/3+1/3]=30000V
(b) How much work is required tobring a positive charge of 5.00 µC from infinity topoint C if the other charges are held fixed?
work done=potential*charge=30000*5*10-6=0.15J
(c) How much additional work isrequired to move the +5.00 µC point particle frompoint C to the midpoint of sideAB?
in the above mentioned way findout the potential at the midpoint.now the work=potential *charge
calculating we will get the answer
