      erm psl help

      state teh effect if any on the period of the pendulum when

      a)a heavier pendulum bob of the same size is used

      b)there are a larger number of oscillations

      c) there is a smaller angle of swing

      d)a longer pendulum is used

      assuming all otehr factors are constant

      TIA

      a) no change in period
      b) assuming there is no air resistance, the period will be the same
      c) no change in period
      d) period will increase

      For question c, angle displacement actually does affect the period of pendulum swing. It's due to some air resistance blah. But in theory, you gotta stick to conventions, and that's the period remains the same.
