A simple pendulum oscillates freely between points A and B.
We now put a peg (nail) at some point C as shown. As the pendulum moves from A to the right, the string will bend at C and the pendulum will go to its extreme points D. Ignoring friction, the point D
A. will lie on the line AB
B. will lie above the line AB
C. will lie below the line AB
D. will coincide with B
