A pendulum bob swings along a circular path on a smooth inclined plane as shown in figure, where \( m=3 \mathrm{~kg}, l=0.75 \mathrm{~m} \), \( \theta=37^{\circ} \). At the lowest point of the circle the tension in the string
P is \( T=274 \mathrm{~N} \). Take \( g=10 \mathrm{~m} \mathrm{~s}^{-2} \).
The tension in the string at the highest position is
(1) \( 166 \mathrm{~N} \)
(2) \( 67.56 \mathrm{~N} \)
(3) \( 68 \mathrm{~N} \)
(4) \( 152 \mathrm{~N} \)
