MHT CET 2023 Physics question
A sting of length 'L' fixed at one end carries a body of mass 'm' at the other end. The mass is revolved in a circle in the horizontal plane about a vertical axis passing through the fixed end of the string. The string makes angle '' with the vertical. The angular frequency of the body is ''. The tension in the string is
Answer: (B)
Solution
This is a conical pendulum. The radius of the horizontal circle is . Horizontal component of tension supplies the centripetal force: , so ,
