Question : A weightless thread can bear tension upto 3.7 𝑘𝑔 wt. A stone of mass 500 𝑔𝑚𝑠 is tied to it and revolved in a circular path of radius 4 𝑚 in a vertical plane. If 𝑔 = 10 𝑚𝑠 −2 , then the maximum angular velocity of the stone will be

a) 4 𝑟𝑎𝑑𝑖𝑎𝑛𝑠/𝑠𝑒𝑐

b) 16 𝑟𝑎𝑑𝑖𝑎𝑛𝑠/𝑠𝑒𝑐

c) √21 𝑟𝑎𝑑𝑖𝑎𝑛𝑠/𝑠𝑒𝑐

d) 2 𝑟𝑎𝑑𝑖𝑎𝑛𝑠/𝑠𝑒𝑐

Answer : option (A)

Solution :

A weightless thread can bear tension upto 3.7 𝑘𝑔 wt. A stone of mass 500 𝑔𝑚𝑠 is tied to it and revolved in a circular path of radius 4 𝑚 in a vertical plane. If 𝑔 = 10 𝑚𝑠 −2 , then the maximum angular velocity of the stone will be
