A proton in a particular electric field experiences an electric force whose magnitude is equal to the weight of the proton. Dete

gavmur [86]

Answer:

Electric field, $E=10^{-7}\ N/C$

Explanation:

It is given that, a proton in a particular electric field experiences an electric force whose magnitude is equal to the weight of the proton such that,

$qE=mg$

$E=\dfrac{mg}{q}$

$E=\dfrac{1.67\times 10^{-27}\times 9.8}{1.6\times 10^{-19}}$

$E=1.02\times 10^{-7}\ N/C$

$E=10^{-7}\ N/C$

So, the magnitude of electric field at the location of the proton is $10^{-7}\ N/C$ . Hence, this is the required solution.
