A particle of unit mass undergoes one -dimensional motion such that its velocity varies according to v(x)=`betax^(-2n)`where `beta`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:

Options

A. `-2nbeta^2x^(-4n-1)`
B. `-2nbeta^2x^(-2n+1)`
C. `-2nbeta^2e^(-4n+1)`
D. `-2nbeta^2x^(-2n-1)`
