What will happen if all the nukes gets detoniated at the same time on this earth & the force produced by that explosion becomes greater then the gravitational force of sun?

There is simply not enough fissionable matterial in the world to cause that effect, even if all of it was detonated in a single bomb in a single place. First, it is not just the gravity of the sun you have to worry about, but the inertial force of the Earth's revolution and the reflection of that force due to the Earth's rotation. You would have to cause a force in the exact opposite direction of the Earth's rotation at the right time to ensure that the force is minimally dissipated. This kind of force would tear the Earth to little pieces which would probably then still orbit the sun at relatively the same distance that it is now.

We have already had many events on earth that have been greater than the possible detonation of every nuclear warhead simultaneously, and none of those have been strong enough to affect our orbit. The earth is just too darn big.
It is not quite correct to think of the force being created by an explosion as being greater than the gravitational force of the sun. For example, the force of a trampoline on your feet is greater than the force of gravity, but only a small amount of energy is involved so you don't actually fly off the surface of the planet.
Someone else will have to help me out with orbital mechanics. I'm pretty sure that if you are in orbit, if you increase your speed you actually will orbit lower, and if you slow down your orbit will grow higher (eg the space shuttle). But I can't reconcile that with either firing your retro-rockets (eg slowing down) in order to re-enter the atmosphere, or firing your big rocket to accelerate out of orbit, to the moon say. I'm sure there is a perfectly good explanation, but I haven't looked it up yet.

Hi. You would have to have them all in one place or they would balance out. The total would be less that the Sun's gravity though.
