Question

A proton of velocity $\left(3\hat{i}+2\hat{j}\right)$ $ms^{-1}$ a field of magnetic induction $\left(2\hat{j}+3\hat{k}\right)$ tesla. The acceleration produced in the proton in $ms^{-2}$ is (Specific charge of proton = $0.96 \times 10^8 C kg^{-1}$)

• A. $2.8 \times 10^8 (2 \hat{i} - 3\hat{j}) $
• B. $2.88 \times 10^8 (2 \hat{i} - 3\hat{j} + 2 \hat{k} ) $
• C. $2.8 \times 10^8 (2 \hat{i} + 3\hat{k}) $
• D. $2.88 \times 10^8 (\hat{i} -3\hat{j}+2\hat{k})$

Answer 1

Answer: (B)

Correct answer is (b) $2.88 \times 10^8 (2 \hat{i} - 3\hat{j} + 2 \hat{k} ) $
