Answer» Solution :Data supplied ` R= 5 xx10 ^(-10) m` ` F = 3.7 xx10 ^(9) N, q_1 =q_2 =q ` (IDENTICAL ) a.F=`(1)/( 4pi in _0) .(q^(2))/( r^(2)) =9xx 10^(9) (q^(2))/( r^(2)) ` ` q^(2) =( FR^(2))/( 9xx 10 ^(9)) =( 3.7xx 10^(9) xx( 5xx 10 ^(10) )^(2))/( 9xx10 ^(9)) =( 3.7xx10 ^(-9) xx 25 x10 ^(-20))/( 9xx10 ^(9)) =( 3.7xx25xx10 ^(-28)) /( 9) ` ` thereforeq= SQRT(( 3.7xx25 xx10 ^(-38))/( 9)) =3.2 xx10^(-19) C ` b . q = ne` "" n= (q)/( e) = ( 3.2xx10 ^(-19))/( 1.6xx 10^(-19)) "" therefore n=2` |
