Answer:
q = -7.691 ×
C
so magnitude of charge is 7.691 ×
C
and negative sign mean charge is negative potential
Step-by-step explanation:
given data
electric potential = −2.36 V
distance = 2.93 mm = 2.93 ×
m
to find out
What are the sign and magnitude of a point charge
solution
we know here that electric potential due to charge is
V =
..............................1
here k is coulomb force that is 8.99 ×
Nm²/C² and r is distance and q is charge and V is electric potential
put here all value we get q in equation 1
V =

-2.36 =

q = -7.691 ×
C
so magnitude of charge is 7.691 ×
C
and negative sign mean charge is negative potential
