The magnitude of the point charge held stationary at the origin and at given electric potential is determined as 3.42 x 10⁻⁶ C.
Magnitude of the charge
The magnitude of the charge held stationary at the origin is calculated as follows;
V = kq/r
where;
- k is Coulomb's constant = 9 x 10⁹ Nm²/C²
- q is the magnitude of the charge = ?
- r is the distance of separation = 1.1 m
Substitute the given parameters into the above equation and solve magnitude of the point charge.
kq = Vr
q = Vr/k
q = (2.8 x 10⁴ x 1.1)/(9 x 10⁹)
q = 3.42 x 10⁻⁶ C
Thus, the magnitude of the point charge held stationary at the origin and at given electric potential is determined as 3.42 x 10⁻⁶ C.
