The displacement of two identical particles executing SHM are represented by equations

x1=4sin⁡10t+π6 and x2= 5 cosωt

For what value of ω energy of both the particles is same?

  • A
    16 unit
  • B
    6 unit
  • C
    4 unit
  • Correct answer
    D
    8 unit

Solution

E1= E2

∴ 12m1ω12A12=12m2ω22A22

but m1=m2

∴ ω12×16=ω22×25

∴ 100×16=ω2×25

ω=8 units

Hence, the correct answer is option: 'D'.
