Question

In a mass s he radius of thpe (neon) ion (ichare e Ne (neon) ion (charge +e) enters a magnetic field of 0.500 T with a speed of 1.00 10 the path is 4.55 cm, what is the mass of the neon ion? radius of the A. 9.11x10-" kg B. 3.32x10 kg C. 4.55x10 kg D. 3.64x 10 kg E. 7.85x10- kg sitively-charged particle is released from rest in a region that has a magnetic field directed to the right. The particle will A. remain at rest. accelerate to the right (4x) C, accelerate up (+y. D. accelerate into the page (-2) E. accelerate out of the page (2) ourt of ngatively-charged particle travels to the right with a velocity v in a s a magnetic field directed up as shown. The direction of the magnetic force on this particle is A. to the right (+x) B. up y). C. down (y) into the page (-z). there is no force on this particle E out of page 7. A charged particle with charge 1.8 C travelling 3.5x10 m/s enters a magnetic field with magnitude 1.20 T What is the force on the charge if the velocity is perpendicular to the magnetic field direction? A. 5.26 N B. 7,56 N C. 8.29 N D. 10.2 N E. 12.1 N

Explanation / Answer

here,

4)

magnetic feild , B = 0.5 T

speed of particle , v = 1 * 10^5 m/s

radius of path , r = 4.55 cm = 0.0455 m

let the mass of ion be m

radius , r = m * v /( q * B)

0.0455 = m * 1 * 10^5 /( 1.6 * 10^-19 * 0.5)

solving for m

m = 3.64 * 10^-26 kg

the mass of ion is D) 3.64 * 10^-26 kg
