ایک ذرہ پر ایک قوت قدامت پسند ہے اگر ______؟
A. It obeys Newton’s Second Law
B. Its work depends on the end points of every motion, not on the path between them
C. Its work equals the change in the kinetic energy of the particle
D. None of these
Explanation
A conservative force (e.g., gravitational or electrostatic) depends only on the initial and final positions, not on the path taken. The work done by a conservative force can be recovered completely, unlike non-conservative forces (e.g., friction). Show/Hide Explanation

A. 3.7 A/m
B. None of these
C. 37 A/m
D. 370 A/m
Explanation
Magnetization (M) is the product of the magnetic field intensity (H) and the magnetic susceptibility (χ):
M = χH
Given:
χ = 3.7 × 10^-3
H = 10^4 A/m
M = (3.7 × 10^-3) × (10^4 A/m)
= 37 A/m

کسی سیارے کے بڑے پیمانے پر اور قطر زمین سے دوگنا ہوتا ہے۔ پینڈولم سیارے کے دوچار ہونے کی مدت ہوگی (اگر یہ زمین پر دوسرا لاکٹ ہے)؟
A. 1/2 second
B. 2√2 seconds
C. None of these
D. 1√2 seconds
Explanation
The formula for the period of a pendulum is T = 2π√(l/g) , where l is the length of the pendulum and g is the acceleration due to gravity. Since the mass and diameter are doubled , the acceleration due to gravity (g) on the planet will be half that of Earth. Therefore, the new period of oscillation will be √2 times the period on Earth, meaning if it was a second's pendulum on Earth, it will be 2√2 seconds on the planet.
