Two charges, charge $A(63C)$ and charge $B(52C),$ are separated by some distance. The magnitude of the electric force on charge B $($due to its interaction with charge A$)$ is $4\mathrm{.}9$ N $.$ What is the magnitude of the electric field at the location of charge B$?$

$($a$)2\mathrm{.}5{10}^4\frac{N}{C}$

$($b$)6\mathrm{.}7{10}^5\frac{N}{C}$

$($c$)1\mathrm{.}1{10}^5\frac{N}{C}$

$($d$)7\mathrm{.}8{10}^4\frac{N}{C}$

$($e$)9\mathrm{.}4{10}^4\frac{N}{C}$
