Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion (A) : A ball connected to a string is in circular motion on a frictionless horizontal table and is in equilibrium.
Reason (R): Magnitude of the centripetal force is equal to the magnitude of the tension in the string.
In the light of the above statements, choose the correct answer from the options given below
y = a sin(βx + γt)wherex and t represent displacement and time, respectively. Then, the dimensional formula for β— γis:
It is a vector quantity. A vector quantity is a quantity having both magnitude and direction. Speed is a scalar quantity and it is a quantity having a magnitude only. Motion in a plane is also known as motion in two dimensions.
The equations of motion in a straight line are:
v=u+at
s=ut+½ at2
v2-u2=2as
Where,
