我算不出來
( 15%)A singly charged ion of mass m is accelerated from rest by a potential d
ifference V.
有個鐵的質量被加速的V還有一個標準磁場
磁場作用是什麼啊
有沒有人知道啊
我看不懂題目啊
幫幫忙好不
記得附上公式和算式
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

你不會怎不去問老師 ?

1+1=2 就這麼簡單

？

你連iron跟ion都分不清

E=mc2

F=ma

準備重修

你是反串的嗎？
