$A$ proton of velocity $(3\hat i + 2\hat j) \, ms^{-1}$ enters a magnetic field of $(2\hat j + 3\hat k) \, T$. The acceleration produced in the proton is (charge to mass ratio of proton $= 0.96 \times 10^8 \, C/kg$)

• A
  $2.88 \times 10^8 (2\hat i - 3\hat j) \, m/s^2$
• B
  $2.88 \times 10^8 (2\hat i - 3\hat j + 2\hat k) \, m/s^2$
• C
  $2.88 \times 10^8 (2\hat i + 3\hat k) \, m/s^2$
• D
  $2.88 \times 10^8 (\hat i - 3\hat j + 2\hat k) \, m/s^2$
