A) \[19.2\times {{10}^{-17}}N\]
B) \[1.92\times {{10}^{-17}}N\]
C) 0.992 N
D) None of these
Correct Answer: B
Solution :
Maximum magnetic field is given by \[{{B}_{0}}=\frac{{{E}_{0}}}{c}\] Here, \[{{E}_{0}}=600V/m\] \[c=3\times {{10}^{8}}m/s\] \[\therefore \] \[{{B}_{0}}=\frac{600}{3\times {{10}^{8}}}\] \[=2\times {{10}^{-6}}T\] Maximum magnetic force imposed on given charge is \[{{F}_{m}}=qv{{B}_{0}}\] \[=2ev{{B}_{0}}\] \[=2\times 1.6\times {{10}^{-19}}\times 3\times {{10}^{7}}\times 2\times {{10}^{-6}}\] \[{{F}_{m}}=1.92\times {{10}^{-17}}N\]
