Who is first men of India who take 9 wicket in one innings .

Name of first lady who goes in universe.

A wt. of 100kg is supported by two rope which are tied to the wt. and are inclinded at angle 45 degree and 30 degree to ht e vertical string.

Two forces acting on a particle are at right angles and are balanced by a third forces making and angle 150 degree with one of them . the greater of the two is 3kg . What are the value of the other two?

A wt. W hang by a string and is drawn aside by a horizontal force until the string makes an angle 60 degree with the verticle . find the horizontal force and tensionnin the string.

Three forces P,Q and R act on particle and keep it in equlibrium If the angle between the force P and Q and between Q and R 120 degree , prove that P=Q=R.

Three equal forces acting at a point are in equalbrium . Show that they are equally inclinded to one another and conversely.

Two fine light string supported a weight W kg and are inclinded to the verticle angle 30 degree and 60 degree . Find the tension in the string.

 The end of a string 23cms long , are atteched to two point A and B in horizontal line. A weight 5 gms is fastened to a point C , of the string . find the tension in the string , if AB=17 cms and Ac = 8 cms when the weight is at rest.

Two string of length 4 m and 5 m are fastened to a particle of mass W kg. theur ends being fastened to point at the same level 6 m apart . find the tensions in the string.

A body of mass 26 N is suspended by two strings 5m and 12 m long their other end being fastened to the extremities of a rode 13 m long . If the rod be so held that the body hangs immediately below the middle point , find the yension of the strings.
