A proton of velocity `(3hati+2hatj) ms^(-1)` enters a field of magnetic induction in the proton in (specific charge of proton `=0.96xx10^(8) Ckg^(-1)`) `[F=q(vec(v)xxvec(B))]`

Options

A. `0.96 xx10^(8) (6hat(i) +9hat(j) + 4hat(k))`
B. `0.96 xx10^(8) (6hat(i) - 9hat(j) - 4hat(k))`
C. `0.96 xx10^(8) (hat(i)-hat(j)-hat(k))`
D. ` 0.6 xx10^(8) ( 5hat(i) - 9 hat(j) - 4hat(k))`

Answer

B

Explanation

`vec(F) = e(vec(v) xx vec(B)) , vec(a) = e/m (vec(v) xx vec(B))`
