Question

Part 1 Find the direction of magnetic force on (a) positive & (b) negative charges moving in magnetic field as shown in the figure. Doubly charged uranium- 235 and uranium 238 are being separated in a mass spectrometer. The masses of ions are 3.90 times 10^-25 kg and 3.95 times 10^-25 kg, respectively and they travel at 2.00 times 10^5 m/s in a 0.250 T. What is the separation between their paths after they hit a target? Use right hand rule to find the trajectories of the ions in B field (diagram)

Explanation / Answer

A)

For positive charge force is leftward

For negative charge force is rightward

B. For positive charge force will into the page

For negative charge force will be out ward of page

3b. F=BQV
