So, here in this question we need to find out the revolution per second which is known as rps.
00:12
So, here from that, ok we need to understand as it is given that the breaking tension of string, breaking tension of string is 45 kg, this is equal to 45 multiplied by 10 newton and that is equal to 450 newton.
00:47
So, the tension in the string, so the tension in the string, in the string when we rotate the mass should be less than 450, right, should be less than of that 450 newton, ok.
01:30
So, this is 450 newton, newton.
01:36
After that as per the condition that means tension should be more than equal to m of omega square r, ok.
01:44
So, from here omega is less than equal to root over of t divided by m r, ok...
