QUESTIONS OF THE DAY
Q1.
A pulley of radius 2 m is rotated about its axis by a force F = 20t - 5t
2
N (where t is measured in seconds) applied tangentially. If the moment of inertia of the pulley about is axis of rotationis 10kgm
2
, the number of rotations made by the pulley before its direction of motion if reversed, is:
A.
more than 9
B.
less than 3
C.
more than 3 but less than 6
D.
more than 6 but less than 9
Q2.
Two identical charged spheres suspneded from a common point by two massless strings of length L are initially a distance d (d << L) apart because of their mutual repulsion. The charge begins to leak from both the spheres at a constant rate. As a result the charges approach each other with a velocity v. Then as a function of distance x between them, the velocity v is proportional to:
A.
x
B.
x
-1/2
C.
x
-1
D.
x
1/2
