answer part (b) and help write the user function bisectionroot

1. The force F acting between a particle with a charge q and a round disk with a radius R and a charge Q is given by the equation: F=20Qqz(1z2+R2z) where 0=8.851012C2/(Nm2) is the permittivity constant and z is the distance to the particle. Determine the distance z if F=0.3N, Q=9.4106C, and q=2.4105C, and R=0.1m. (a) (b) Use the user-defined function BisectionRoot with interval of [0.1,0.2]
