Question

Wave is travelling on a stretched string fixed at one end as shown in the figure. The resultant force acting on particle at point A is

• A. Zero
• B. In upward direction
• C. In downward direction
• D. Can't be determined

Answer 1

The correct option is A Zero

At point A, the particle present is acted by force from the string left to it and by force from the clamp. The force from the string is balanced by the clamp's force, and resultant force becomes zero on point A and end remains fixed.
