Cause i saw it and i know it
I believe the answer is a) 15 joules
Answer:
4347.8 m/s
Explanation:
It is given that the radius of the circular path traversed by proton and electron is same. Also, we know that magnitude of charge on an electron and proton is same. Magnetic field strength is same for both.
![\frac{m_ev_e^2}{r}=qv_eB\\\frac{m_pv_p^2}{r}=qv_pB\\](https://tex.z-dn.net/?f=%5Cfrac%7Bm_ev_e%5E2%7D%7Br%7D%3Dqv_eB%5C%5C%5Cfrac%7Bm_pv_p%5E2%7D%7Br%7D%3Dqv_pB%5C%5C)
Take the ratio:
![m_ev_e=m_pv_p\\\Rightarrow v_p=\frac{m_e}{m_p}v_e\\\Rightarrow v_p=\frac{1}{1840}\times 8.0\times 10^6 m/s\\\Rightarrow v_p=4347.8m/s](https://tex.z-dn.net/?f=m_ev_e%3Dm_pv_p%5C%5C%5CRightarrow%20v_p%3D%5Cfrac%7Bm_e%7D%7Bm_p%7Dv_e%5C%5C%5CRightarrow%20v_p%3D%5Cfrac%7B1%7D%7B1840%7D%5Ctimes%208.0%5Ctimes%2010%5E6%20m%2Fs%5C%5C%5CRightarrow%20v_p%3D4347.8m%2Fs)
The first step in problem solving is of
course, identifying the problem. How could you solve the problem if there is no
problem in the first place? When one gets to identify the problem, the next
step is gathering of information to know more about the problem. One needs to
get to know and examine the pros – the benefits – and con – the flaws – of the
problem well. After doing all the needed data gathering and possibly,
experimentation, when can start looking for the possible solutions of the
problem.
