sir as we know that work done against gravitational force =+delta U ...but if we take the body from infinity towards earth then work done should be = -delta U ..FROM this we find that GPE at a distance r from earth surface is +GMm/r

if u r moving towards the center that means u r inside the source and the points behind u will will attract u towards them n points in front of u will attract u towards them ...........so the net force will decrease .................................but if u r moving towards the surface their is nothing behind u to attract u ..

but sir at black whole this statement would wrong as we move deeper and deeper in black whole gravity increases and we reached to the singularity and sir acc to newton gravitational fomula f=gMm/r*r if r is small then f is large and if r=0 then force become infinite... bt thats not true sir so formula is wrong??
@ritheshbannu8305
@ritheshbannu8305 8 жыл бұрын
hey bro. this law nt made for blackhole. but still we can apply this law for it. bcz blackhole have large gravity. so up to some distance from surface the gravity will be more that even light can't escape from that. so all photons will be suck by the dence matter. this constitute blackhole.
@ritheshbannu8305
@ritheshbannu8305 8 жыл бұрын
so their is ntg till some space in blackhole. the only occupation of dense matter is in middle. so when we move from the dark surface to the dence matter surface in blackhole. as the distance is decreasing in between both center of masses. but the mass of bodies unchanged hence grvaity increases. but when it touches the surface of the dence matter and go deeper further the force start decresing.

sir you have written : for bringing mass from A TO B , Va-Vb = Wab /m then for bringing mass from INFINITY TO A, V(infinity) - Va = W (INFINTY A) /m so it is 0- Va = W (infinity A) /m

@nbclasses9448 10 жыл бұрын
i feel it is better if u write like this : i.e for bringing mass from a to b vb- va = Wab/m = - Wba/m and for bringing mass from infinity to A Va- V (infinity) = Va = W (infinity to A) /m = - W( from A to infinity)/m if we assume vb>va and va> v(infinity) i think that would have avoided the confusion in students sir....
