A particle is moving in a vertical circle. The tension in the string when passing through two positions at anele of 30$\xb0$ and 60$\xb0$ from vertical (the lowest position) are ${\mathrm{T}}_{1}\mathrm{and}{\mathrm{T}}_{2}$ respectively, then:

1. ${\mathrm{T}}_{1}={\mathrm{T}}_{2}$

2. ${\mathrm{T}}_{2}{\mathrm{T}}_{1}$

3. ${\mathrm{T}}_{2}{\mathrm{T}}_{1}$

4. Tension in the string always remains the same.
