An electron accelerateo h1na5/no w5us thrqr qxj)6y/nn 4) dta9sough a potential difference of $7\,kV$. How much work is done on the electron by the field?
A. $1.1\times10^{-18}$
B. $1.1\times10^{-15}$
C. $1.1\times10^{-12}$
D. $1.1\times10^{-9}$
参考答案: B
本题详细解析:
Explanation: Using $V=\frac{q}{W}$ from the data booklet, W=Vq =($7\times10^3V$)($1.6\times10^{-19C}$) =$1.1\times10^{-15}J$
