JS1.pdf mp-start Problem 1 Name: Section: Phys 214 Spring 2025 A sulfate ion SO4* (mass 1.595 x 10* kg) is initially at rest on the origin of a Cartesian coordinate system. A potassium ion K* (mass 6.492 x 10 kg) is placed, initially at rest, at (2.50 mm, 0). Remember that vectors have both magnitude and direction. In this problem, give the direction of vectors as either +% or %. a) What is the electric force acting on the sulfate ion? b) What is the acceleration of the sulfate ion? ) What is the electric force acting on the potassium ion? The potassium ion is replaced by a chloride ion CI\" (mass 5.887 x 107% kg) at the same location. d) What happens to the magnitude of the electric force on the sulfate ion? Circle one and explain your answer. increases / decreases / stays the same e) What happens to the direction of the electric force on the sulfate ion? Circle one and explain your answer. changes / stays the same f) What happens to the magnitude of the sulfate ion's acceleration? Circle one and explain your answer. increases / decreases / stays the same
