Electrostatics Lab Activity 3 (1/A) Analysis of Coulomb's Law Part A: Determining the force on the pith ball at an instance in time due to an influence. A student performing an experiment to determine the strength of the electrostatic interaction between 2 pith balls identical both size and mass (0.221 kg). Evidence of the interaction between the charged pith ball A that is place near suspended charge pith ball B. is shown pith ball B in the deflected as shown below. 20%% Pith ball Determine the Force electric acting on pith ball B. ( Besure to provide a reason solution induding a free body diagram and physics principle)
