Find the electric field intensity in which a proton experiences a force equal to its own weight. (Take, `m_(p)= 1.67 xx 10^(-27)kg, e^(-) = 1.6 xx 10^(-19)C`)

Explanation

Given, mass of proton, `m_(p)= 1.67 xx 10^(-27)kg`,
charge on proton, `q_(p)= e^(-) = 1.6 xx 10^(-19)C`,
`g=10 m//s^(2) and E`= ?
`therefore` Electric field intensity, `E= (F)/(q)= (m_(p)g)/(q)`
`=(1.67 xx 10^(-27))/(1.6 xx 10^(-19)) xx 10`
`rArr E= 1.04 xx 10^(-7)V//m`
