### Sample Questions

Question 1
A thin horizontal circular disc is rotating about a vertical axis passing through its centre. An insect is at rest at a point near the rim of the disc. The insect now moves along a diameter of the disc of reach its other end. During the journey of the insect, the angular speed of the disc
 first increases and then decreases. continuously increases continuously decreases remains unchanged
Question 2
Work done in increasing the size of a soap bubble from a radius of 3 cm to 5 cm is nearly(surface tension of soap solution = 0.03 Nm1)
 0.4 π mJ 0.2 π mJ 2 π mJ 4 π mJ
Question 3
Two identical charged spheres suspended froma common point by two massless strings of length  are initially a distance d (d << l)apart because of their mutual repulsion. The charge begins to leak from both the spheres at aconstant rate. As a result the charges approach each other with a velocity v. Then as a function of distance x between them
 v ∝ x1/2 v ∝ x-1 v ∝ x -1/2 v ∝ x
Question 4
If a wire is stretched to make it 0.1% longer, its resistance will
 increase by 0.05% decrease by 0.05% decrease by 0.2% increase by 0.2%
Question 5
A car is fitted with a convex side–view mirror of focal length 20 cm. A second car 2.8 m behind the first car is overtaking the first car ata relative speed of 15 m/s. The speed of the image of the second car as seen in the mirror of the first one is
 10 m/s 1/10 m/s 1/15 m/s 15 m/s
Question 6
A Carnot engine operating between temperatures T1 and T2 has efficiency increases to 1/3. Then T1 and T2 are, respectively :
 310 K and 248 K. 372 K and 330 K 330 K and 268 K 372 K and 310 K
Question 7
A resistor R and 2µF capacitor in series inconnected through a switch to 200 V direct supply. Across the capacitor is a neon bulb that lights up at 120 V. Calculate the value of R make the bulb light up 5 s after the switch has been closed (log102.5 = 0.4)
