what is physics

          First law of motion

1. An object will continue moving uniformly until

          (a)  The resultant force acting on it begins to decrea

(b)  The resultant force on it is zero

          (c)  The resultant force is at right angle to its rotation

          (d)  The resultant force on it is increased continuously

• Inertia is that property of a body by virtue of which the body is

          (a)  Unable to change by itself the state of rest

          (b)  Unable to change by itself the state of   

                 uniform   motion

          (c)  Unable to change by itself the direction of  

                   motion

          (d)  Unable to change by itself the state of rest                  

                  and of uniform linear motion

what is rest

1. In the above Question, if the string C is stretched slowly, then

          (a)  The portion AB of the string will break

          (b)  The portion BC of the string will break

          (c)  None of the strings will break

       (d)     None of the aboveWhen the spring C is stretched slowly, the tension in A is greater than that of C, because of the weight mg and the former reaches breaking point earli
