In the diagram, 91 = -3.33*10^-9 C and q2 = -5.22"10^-9 C. The electric field at
point P is zero. What is the distance
from P to q2?
91
92
P
?
+
0.255 m
(Remember, E points away from + charges,
and toward - charges.)
(Unit = m)

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
