MHT CET 2025 Physics question
An inextensible string of length '' fixed at one end, carries a mass 'm' at the other end. If the string makes revolutions per second around the vertical axis through the fixed end, the tension in the string is [The string makes an angle with the vertical]
Answer: (C)
Solution
This is a conical pendulum. Angular speed rad/s. Radius of the circle is . Horizontal component of tension provides the centripetal force: \sin$θ =
