When a force F₁ acts on a particle, frequency is 6 Hz and when a force F₂ acts, frequency is 8 Hz . what is the frequency when both the forces act simultaneously in same direction?

Options

  1. A12 Hz
  2. B25 Hz
  3. C10 Hz
  4. D5 Hz

Correct answer

C. 10 Hz

Step-by-step solution

aligned & F=m r ^2=m r (2 m r n)^2=4 ^2 m r^2 & F 2 n^2 aligned aligned F & =F₁+F₂ n^2 & =n₁^2+n₂^2 n & = n₁^2+n₂^2 n & = (6)^2+(8)^2 n= 100 & =10 ~Hz aligned
