Correct answer is (d) 108C kg-1

Q. A charged particle moving with veiocity $4 \times 1 0^{6} m s^{- 1}$
enters perpendicuiar to a magnetic field $B = 2 Wb m^{- 2} .$
It moves in a circular path of radius 2 cm, then charge
per unit mass is

$1 0^{2} C k g^{- 1}$

$1 0^{3} C k g^{- 1}$

$1 0^{4} C k g^{- 1}$

$1 0^{8} C k g^{- 1}$

Correct answer is (d) $1 0^{8} C k g^{- 1}$
