Question

If the charge on a body is increased by 2 C , the energy stored in it increases by 21 % . The original charge on the body in coulomb is If the charge on a body is increased by 2 C , the energy stored in it increases by 21 % . The original charge on the body in coulomb is

Quantrex Academy · Accepted Answer

Correct answer: B. 20

Energy stored, E q^2 aligned E₁ E₂ & = ( q₂ q₂ )^2 100 121 & = ( q q+2 )^2 ( 10 11 )^2 & = ( q q+2 )^2 10 11 & = q q+2 10 q+20 & =11 q q & =20 C aligned [OBJECT END

If the charge on a body is increased by 2 C , the energy stored in it increases by 21 % . The original charge on the body in coulomb is If the charge on a body is increased by 2 C , the energy stored in it increases by 21 % . The original charge on the body in coulomb is
