Questions
The potential energy of a particle in force filed is U = where A and B are positive constants and ‘r’ is the distance of particle from the centre of the field . For stable equilibrium , the distance of the particle is
detailed solution
Correct option is D
for stable equilibrium F=-dUdr=0 -ddrAr2-Br=0 A(-2r-3)-B(-1r-2)=0 ⇒r=2ABTalk to our academic expert!
