B

4.8×10−10stat 6mucoulomb4.8 \times 10^{- 10}stat\mspace{6mu} coulomb

C

1.76×1011coulomb/kg1.76 \times 10^{11}coulomb/kg

D

∣8∣×10−15Hz|8| \times 10^{- 15}Hz

Answer

1.76×1011coulomb/kg1.76 \times 10^{11}coulomb/kg

Explanation

Solution

em=1.6×10−199.1×10−31=1.76×1011C/kg\frac{e}{m} = \frac{1.6 \times 10^{- 19}}{9.1 \times 10^{- 31}} = 1.76 \times 10^{11}C/kg
