Acharge +q is located at the origin, while an identical charge islocated on the x axis at x= +0.50 m. a third charge of +2 q islocated on the x axis at such a place that the net electrostaticforce on the charge at the origin doubles, its direction remainingunchanged. where should the third charge be located.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
