Five identical positive charges +49.8 nC are placed equally spaced around a circle of radius 14.8 cm in the xy-plane (i.e. z = 0.0 cm) centred at the origin. (answer to 1 decimal place.)

(a) What is the magnitude of the resultant field at the centre of the circle?

(b) An additional charge +49.8 nC is placed at coordinates (-6.4, 8.4, 0.8) cm. What is the magnitude of the resultant field at the centre of the circle now?
