Potential Energy Graph

Potential Energy v/s displacement curve for one dimensional conservative field is shown.Force at A & B is respectively

(A) Positive , Positive

(B) +ve , - ve

(D) - ve. - ve

Plz use MAGNIFIER if img is not clear

Sorry :( for inconvenience

we know tat -dU/dx=F

we also know tat dU/dx is the slope of tangent to teh curve at any point x

slope of tangent to teh curve at point A will be negative hence force will be positive

slope of tangent to teh curve at point B will be positive hence force will be negative....

Anonymous Why slope of tangent will be negative at A abd slope of tangent + at B
