A point mass m is suspended by means of a light metallic wire The mass is given enough horizontal velocity so that it moves in a vertical circle Now temperature is increased but the wire continues to move in a circle of increased radius if T_(H) and T_(1)are the value of tension in the wire at its highest and lowest point respectively then due to increase in temperature the value of (T_(1)-T_(H)) will: |

Answer» DECREASE `u=sqrt(5gL) &v=sqrt(gL)` `T_(L) = MG+mu^(2)/L = 6mg` `T_(H)=mg-(mv^(2))/L = 0` `(T_(L)-T_(H))=6mg`ie independent of temperature
