Alpha particles of charge q = +2e and mass m = 6.6e-27 kg are emitted from a radioactive source at a speed of 1.5e7 m/s. What magnetic field strength would be required to bend these into a circular path of radius r = 0.23 m?
I've been doing
qvB=mV^2/r
(2*1.6e-19)(1.5e7)B=(6.6e-27)(1.5e7)^2…
And got B=0.3528T
What am I doing wrong? What is the correct answer?

ur equation is right , recheck ur calculations .

You forgot to divide by the radius on the right side of the equation (with the numbers)
