Question

Q.6. A particle moves along the x-axis under a force
F=- K1X + K2x2 where K, and Ky are constants. The force is conservative
(a) for any K1 and K2
(b) only if K2 is zero
(c) only if Ki is zero
(d) only if K2 is negative ​

Answer 1

Answer:

U=5x  

2

−20x+2

F=−  

dx

dU

​  

=10x−20=0 at mean position x=2

Amplitude =2−(−3)=5

Maximum X-coordinate =5+2=7m
