It is also known that the mean-life time of P is the same as the half-life time of Q. then which of the following is correct? A. The decay rate of P is larger than that of Q B. The decay rate of Q is larger than that of P C. The decay constant of P is less than that of Q D. The decay rate of P and Q will be same initially

3. An object is moving away from a vertical concave mirror of focal length 25 m. When the distance of the object is 100 m, the velocity of the object is 5 m/s and it accelerates at the rate of 2 m/s2. The distance of the object from the image after 5 sec is A. 300 m B. 120 m C. 150 m D. 90 m

6. If E = energy, G = gravitational constant, I = impulse and M = mass,the dimension of (GIM2)/E2 are same as that of A. mass B. length C. time D. force

7. A car moving at a speed of 20 km/hr stops by applying brakes after travelling 5m. If the same car is moving at 40 km/hr, the stopping distance after applying brakes will be A. 10m B. 20m C. 5m D. 1m

Each paper is for 100 marks and 80% is based on MCQs and 20% is on short type questions.

Experimental investigations show that the intensity of solar radiation is maximum for a wavelength 480 nm in the visible region.
Estimate the surface temperature of sun. Given Wein’s constant b = 2.88 × 10–3 mK.
(A) 4000 K (B) 6000 K (C) 8000 K (D) 106 K
Ans : (B)
Hints : λm × T = b
λm = 480 nm

3. Two mirrors at an angle θº produce 5 images of a point. The number of images produced when θ is decreased to θº – 30º is
(A) 9 (B) 10 (C) 11 (D) 12
Ans : (C)
Hints : No. of images = 5
∴ θ = 60º
