The position x of a particle at time t is given by x=V0a(1−e−at), where V0 is constant and a>0. The dimensions of V0 and a are
A particle of unit mass undergoes one-dimensional motion such that its velocity varies according to v(x)=βx−2n ,where β and n are constants and x is the position of the particle. The acceleration of the particle as a function of x, is given by :
