NEET & AllMS NEET & 27. A homogeneous bar of length L and mass M is at a distance h from a point mass ma shown. The force on m is F, then find F |

Answer» tion:Consider a small element DX of the rod at a distance X from the left END of the rod.Mass of this small element is DM = M/LdxDistance of this small element from mass m is x + h.Force on m due to this small element is dF = GmdM/(x +h)^2To get the TOTAL force F on the mass m we integrate dF from x= 0 to x = LF = ∫^x=L and x = 0 GmM/L dx/ (x + h)^2 = - GMm/L (1/L + h - 1/L) = GmMh/L(L +h)Thus the force on m due to homogeneous bar is GMmh/L(L +h).Read more on Brainly.in - brainly.in/question/12976243#readmore |
