A body performs SHM along the straight line segment ABCDE with C as the mid point of segment AE (A and E are the extreme position for the SHM). Its kinetic energies
at B and D arc each one fourth of its maximum value. If length of segment AE is 2R, then the distance between B and D is
detailed solution
Correct option is C
When the particle crosses D, its speed is half the maximum speed∴ V=vmaxRR2−x2 or vmax2=vmaxRR2−x2 or x=32R∴ Distance BD=2x=3RTalk to our academic expert!
