Answer:
Pendulum will swing by an angle 0.666π
Step-by-step explanation:
We have given arc =
And length of the pendulum l = 150 cm
Length of the pendulum will be equal to radius of the pendulum so r = 150 cm
Arc is given by
So
So pendulum will swing by an angle 0.666π
Answer:
The answer is , or the first option.
