Part3:Calculate the unit vector corresponding to vector rVector r: ( , , )Part5:What is the electric force that the electron exerts on the alpha particle?Vector F on the alpha particle: ( , , )

A helium nucleus, which for historical reasons is also called an "alpha particle", contains two protons and two neutrons, so its charge is +2 x 1.6 x 10 19 C. It is located at (5 x 10-2, -9 x 10-2, -22 x 10-2) m. An electron, whose charge is - 1.6 x 10-19 C, is located at ( 11 x 10-2, 19 x 10-2, -6 x 10-2) m. We will calculate the electric force exerted on the electron by the alpha particle, one step at a time. Part 1 Calculate the vector 7 that points from the alpha particle to the electron: 7 = ( i i i m Save for Later Attempts: 0 of 4 used Submit Answer Part 2 Calculate the magnitude of 7 : m Save for Later Attempts: 0 of 4 used Submit
