A proton and an alpha particle are accelerated, using the same potential difference How are the de Brogie wavelengths lambda_p and lambda_alpha are related to each other?

Answer»

SOLUTION :By DE Broglie wavelength, `lambda=h/SQRT(2mqV) lambda_alpha 1/sqrt(mq)`
Then `lambda_p/lambda_alpha=(sqrt(m_alpha q_alpha)/(sqrtm_pq_p))=(sqrt(4m_pxx2e)/(sqrt(m_pxxe))=sqrt(8)/1`
