# If the force of attraction between two unit masses (1 kg each) kept 1 km apart is taken as unit force and the unit of energy in this system is called ‘eluoj’ (joule written in reverse order) then the relation of ‘joule’ and ‘eluoj’ is [G = 6.67 × 10–11 Nm2 kg]–2        (a)    1 eluoj = 6.67 × 10–17 joule        (b)    1 eluoj = 6.67 × 10–14 joule        (c)    1 eluoj = 10–4 joule        (d)    1 eluoj = 6.67 × 10–9 joule 7 years ago

(b)

Let’s say force ‘notwen’ (newton written in reverse order) we know

1 notwen = G  = G = 106 notwen m2kg–2

But G = 6.67 × 10–11 Nm2kg–2

\ 1 notwen = 6.67 × 10–17 newton

1 eluoj = 1 Nowten × 1 km = 6.67 × 10–14 newton × 1 m

= 6.67 × 10–14 Joule
