12 charges each of magnitude Q is placed equidistant on a circle of radius R as shown in the figure. A charge of magnitude q is placed at the centre of the circle. If one of the charges from the circumference of the circle is removed, the force on q is
1
\(\frac{kqQ}{R^2}\) away from the position of the removed charge
2
\(12\frac{kqQ}{R^2}\)away from the position of the removed charge
3
\(\frac{kqQ}{R^2}\) towards the position of the removed charge
4
\(11\frac{kqQ}{R^2}\) towards the position of the removed charge
