我算不出来
( 15%)A singly charged ion of mass m is accelerated from rest by a potential d
ifference V.
有个铁的质量被加速的V还有一个标准磁场
磁场作用是什么啊
有没有人知道啊
我看不懂题目啊
帮帮忙好不
记得附上公式和算式
It is then deflected by a uniform magnetic field (perpendicular to the ion’s
velocity) into a semicircle of radius R. Now a doubly charged ion of mass m’
is accelerated through the same potential difference and deflected by the same
magnetic field into a semicircle of radius RR. What is the ratio of the masse
s of the ions?

V=IR

你不会怎不去问老师 ?

1+1=2 就这么简单

？

你连iron跟ion都分不清

E=mc2

F=ma

准备重修

你是反串的吗？
