You rub a balloon against your head giving the balloon a large negative charge of balloon = -6.3x10C. The balloon is now the source for an electric field. Point X is 5 cm away from the balloon and point Y is 10 cm away. We will use two different test particles to explore the balloon's electric field. Particle A has a charge qa=+2.5 x 10-1°C and particle B has a charge of qs = +5.0 x 10°C. 1. At position X, we measure an electrostatic force of 1.8x10N acting on particle A. What is the magnitude and direction of the electric field strength that particle A experiences at point X? • X • Y 2. No calculations required (qualitative/conceptual answer). If you place particle B at point X instead of particle A, how does the electric field strength change? 3. You place a new and mysterious test particle at point X and observe that it experiences an electrostatic force of 2.1 x 10-N in a direction away from the balloon. What is the charge of this mysterious particle?
