Paragraph: The time-period of a simple pendulum performing simple harmonic motion, having length is given T =2 ~g This formula holds good if following conditions are satisfied. (i) String is massless and extensible. (ii) Bob is a point mass. (iii) Angular displacement about mean position is very small, and (iv) Length of string is very small as compared to the radius of earth ( R _ e ) . Question: Now the water of bo

Options

  1. A(A)=1
  2. B1
  3. C1
  4. DNone of these

Correct answer

B. 1

Step-by-step solution

When water freezes it rotates T ₃=2 2 R ^2 5( ~L + R ) +( L + R ) g T ₃ T ₂ OR Ice will rotate therefore system has less translation KE, hence for same amplitude average speed is less. So time period will increase.
