K.E of an object depends upon mass of the object and velocity of the object. find the formula of K.E using dimensional analysis |
| Answer» E know that,The dimension of ENERGY [E]=[M1L2T−2]The dimension of mass [M]=[M1L0T0]Dimension of VELOCITY[V]=[M0L1T−1]Let [E]=k[M]X[V]yWhere k is the proportionality constant which is a dimensionless quantity.Therefore,[M1L2T−2]=k[M1L0T0]x[M0L1T−1]ySo, x=1,y=2Thus, We haveE=kmv2It is found that k=21Hence, E=21mv2hope you like my answer so follow me | |
