This is what I did.
r = (m*v) / (qB)
To find v, v= sqrt( 2*q*V/m) = 37013.9
and I put this number and the given numbers to find 'r', but I got it wrong. What did I do wrong?

Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au2+), each with a mass of 3.27 × 10-25 kg. The ions are accelerated from rest through a potential difference of 2.20 kV. Then, a 0.530-T magnetic field causes the ions to follow a circular path. Determine the radius of the path.
1a) A charged particle with a charge-to-mass ratio of |q|/m = 5.7 × 108 C/kg travels on a circular path that is perpendicular to a magnetic field whose magnitude is 0.55 T. How much time does it take for the particle to complete one revolution? 1b) Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au2+), each with a mass of 3.27 × 10-25 kg. The ions are accelerated from rest through a potential difference...
Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au^2+), each with a mass of 3.27*10^(-25) kg. The ions are accelerated from rest through a potential difference of 1.10 kV. Then, a 0.490 T magnetic field causes the ions to follow a circular path. Determine the radius of the path.
Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions (Au^2+), each with a mass of 3.27 times 10^-25 kg. The ions are accelerated from rest through a potential difference of 2.20 kV. Then, a 0.710-T magnetic field causes the ions to follow a circular path. Determine the radius of the path.
2. The Mass Spectrometer (8 pts): Sodium ions (charge te) are accelerated from rest at plate A through a voltage difference of Δν-1 kV to plate B. Some of the ions pass through a small slit in plate B to enter into a region of uniform magnetic field (the shaded region in the diagram) (a) Which plate is at a higher potential, A or B? Calculate the speed of the Na+ ions when they reach the slit in 5 plate...
Please tell me what I did wrong or why I got -4 thanks! a ie the circuit shown, the capacitor is initally uncharged, and '-40 v. At time r-O,switch S is 40 V 0.50 M ? IE r denotes the time constant, find the charge on capacitor whenr 4 cvle n) If t denotes the time constant, find the approximate current through the resistor when b) A particle with charge 6.00 ?C initially moves with vel If it encounters a...
I have already tried (5*F1*R)/2 and -(5*F1*R)/2. None worked. Not sure what I did wrong. Please Help. Three forces are exerted on the disk shown in the figure below, and their magnitudes are F3 = 2F, = 2F. The disk's outer rim has radius R, and the inner rim has radius R/2. As shown in the figure re tangent to the outer rim of the disk, a tangent to the inner rim. F3 is parallel to the x axis, F2...
please explain #15 throughly. detailed. i got it qrong on thw exam? why did I get the B part wrong? was I suppose ro add 90+35? 14. (10 points) A projectile is launched from ground level with an initial speed of 65 m/s at an angle of 55° above the horizontal. It strikes a target in the air 3 seconds later. What are the horizontal and vertical distances from where the projectile was launched to where it hits the target?...
