Question

The potential energy of a particle is given by V=V₀ [(a/x)¹² - (b/x)⁶ ]

(a) The constants a and b are dimensionless

(b) The constants a and b have same dimensions

(c) V versus x graph intersects the x-axis at only one point

(d) V versus x graph has only one minima

Answer 1

NO (a) The constants a and b are not dimensionless

YES (b) The constants a and b have same dimensions

NO (c) V versus x graph intersects the x-axis at two points

NO (d) V versus x graph has two minimas
