Question

a body having + 10 coulomb charge on it is touched To an another charged body be for sometime after separating both it is found that the body processes + 3 coulomb charge Now recharge on the body B initially was ​

Answer 1

charge on body A = +10 C

let charge on body B = q

body A is touched to an another charged body B for sometime after separating both it is found that the body processes +3 C charge.

so, net charge on system of bodies = (10 + q)

after seperation, charge on body A = charge on body B = (10 + q)/2 = 3C

or, 10C + q = 6C

or, q = 6C - 10C = -4C

hence, initially, charge on body A was -4C

hence, initially, charge on body A was -4C

Answer 2

$\huge\bold\purple{Answer:-}$

charge on body A = +10 C

let charge on body B = q

body A is touched to an another charged body B for sometime after separating both it is found that the body processes +3 C charge.

so, net charge on system of bodies = (10 + q)

after seperation, charge on body A = charge on body B = (10 + q)/2 = 3C

or, 10C + q = 6C

or, q = 6C - 10C = -4C

hence, initially, charge on body A was -4C

hence, initially, charge on body A was -4C
