Question

The rate of doing work by force acting on a particle moving along x-axis depends on position $x$ of particle and is equal to $2x$. The velocity of the particle is given by the expression.

• A. ${\left[\frac{3x^2}{m}\right]}^{\frac{1}{3}}$
• B. ${\left[\frac{3x^2}{2m}\right]}^{\frac{1}{3}}$
• C. ${\left(\frac{2mx}{9}\right)}^{\frac{1}{2}}$
• D. ${\left[\frac{m{x}^2}{3}\right]}^{\frac{1}{2}}$

Answer 1

The correct option is A ${\left[\frac{3x^2}{m}\right]}^{\frac{1}{3}}$

correct option $\left(A\right)$
