A) 8 N in z-direction
B) 8 N in y-direction
C) 4 N in y-direction
D) 4 N in z-direction
Correct Answer: A
Solution :
| [a] \[\overset{\to }{\mathop{F}}\,=q\left( \overset{\to }{\mathop{V}}\,\times \overset{\to }{\mathop{B}}\, \right)\] |
| \[=2\times {{10}^{-6}}\left[ (2\hat{i}+3\hat{j})\times {{10}^{6}}\times 2\hat{j} \right]\] |
| \[=2\times 4\hat{k}=8N\]in Z-direction. |
