Two point charges, initially 2.0 cm apart, experience a 1.0 n force. if they are moved to a new separation of 8.0 cm, what is the electric force between them?

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.

i don't know that i agree with that but what's the question ?

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

the components of a vector are the parts of the vectors that are to each other.
