If a street light of mass M is suspended from the end of a uniform rod of length L in different possible patterns as shown in figure, then

Options

  1. Apattern A is more sturdy
  2. Bpattern B is more sturdy
  3. Cpattern C is more sturdy
  4. Dall will have same sturdiness.

Correct answer

A. pattern A is more sturdy

Step-by-step solution

Pattern A is more sturdy because the moment of the tension about the fulcrum is maximum in A to counterbalance the moment of m g acting from the centre of mass of the rod.
