Hello everyone, we are going to understand this question.
00:05
Here, given in the question, mass of block, mass of block, that is represented by m1, which is 1 kilogram, mass of string, mass of string, that is represented by m2, which is 1 kilogram, and length of string, length of string, that is represented by l, which is 1 meter gravitational acceleration gravitational acceleration g that is given 10 meter per second square let's draw the free body diagram for this now weight of the block that is working vertically downward and g and tension at the lowest point that is represented by t1 in the part a let the tension in the string at the lowest point be t1 let the tension in the string t -1 t -1 at lowest point b t -1.
02:02
So we can write t -1 is equal to m1 into g.
02:08
T -1 is equal to m1 into g.
02:12
Here value of m1 is 1 kg and value of g is 10.
02:16
So t1 is equal to 10 newton.
02:21
Now solving part b.
02:24
Tension in string at mid of the rope.
