Question

A charged particle carrying charge 1μC is moving with velocity  (2\(\hat{i}\) + 3\(\hat{j}\) + 4 \(\hat{k}\)) ms^-1 . if an external magnetic filed of  (5\(\hat{i}\) +  3\(\hat{j}\) - 6\(\hat{k}\)) x 10^-3 T exists in the region where the particle is moving then the force on the particle is \(\overline{F}\) x 10^-9 . The vector \(\overline{F}\) is

Answer 1

(4)  -30\(\hat{i}\) +  32\(\hat{j}\) - 9\(\hat{k}\)
