Question 4 Not yet a n 5w ered Marked out of 2.00 X\" Flag question To analyze charged particles, they must be accelerated to very high speeds using electric fields. A calcium ion {q : +2e, m = 6.65 x 10'25 kg} is accelerated from rest across the gap between two charged, parallel plates. The Jon accelerates from the positively charged plate, straight towards the negatively charged plate. The voltage difference between the plates is 2000 V. ._. Calculate the velocity of the calcium ion when it reaches the negatively charged plate. Answer in units of meters per second. using appropriate scientific notation. Answenl I Question 5 Not vet answered Market: out of 2.30 if Flag question The calcium ion from the previous question is launched into a region with a magnetic field strength of 1.2 T. The magnetic eld is oriented perpendicuior to the velocity of the ion. Recall the properties of the calcium ion: q : +2e. m = 6.65 x1025 kg. If the ion's velocity is 5.4 X104 mfs, calculate the radius of curvature for the ion's motion inside the magnetic field. Answer in units of meters rounded to 4 decimal places. Answer.
