Question 1 Not yet a n 5w ered Marked out of 2.30 'r' Flag question Question 2 Not g-'et answered Marked out of 2.00 t;' Flag question ll An atomic nucleus can be modeled as a single object with a charge of ".Q" "Q" is equal to the number of protons in the nucleusr multiplied by the elementary charge. A sodium atom's nucleus contains 11 protons. The nucleus exerts an electrostatic force on an electron orbiting 8.75 x 10'\" m away. Calculate the MAGNITUDE of the electrostatic force the sodium nucleus exerts on the electron. Express your answer in units of Newtons, using scientific notation. Answer. I I A physicist is studying the electric field between two atomic nuclei [see the image below). The drawing is NOT to scale. Nitrogen P Oxygen nucleus nucleus The point "P" is located 0.89 x 10'10 m from the nitrogen atom and 1.43 x 10'10 m from the oxygen atom. Calculate the direction and magnitude of the net electric field at point P. Answer in units of Hit: using scientific notation. When expressing field direction, treat "towards Oxygen" as the positive direction and "towards Nitrogen" as the negative direction. AnswecI I Question 3 A calcium ion {q = +2e, rn : 6.65 x1025 kg) and an oxygen ion (q 2 -2e. rn = 2.66 x 10'25 kg] are Not yet each launched at the same velocity into a magnetic field oriented perpendicular to the velocity of answered Marked Out of the Ions (see image below]. 3.00 '3' Flag question ions enter from theie. :> ' ' ' ' ' Both Ions * r ' ' have the SAME - . - - - VELOCITY!
