Class 11PhysicsWork, Energy, Power and CollisionWork Energy Theorem and Conservation of Mechanical Energy
EasyThe mass of a pendulum bob is $50 \ gm$. The bob is released from a horizontal position $A$ as shown in the figure. If the length of the pendulum is $1.5 \ m$,what will be its kinetic energy when it reaches the lowest point $B$ of its path? (Take $g = 10 \ m/s^2$)
- A$15 \times 10^{-1} \ J$
- B$7.5 \times 10^{-1} \ J$
- C$5 \times 10^{-1} \ J$
- D$2.5 \times 10^{-1} \ J$
