Explanation Magnetic force is given by F = q(v × B), perpendicular to both velocity v and magnetic field B. Electron moves along x-axis, B is in xz-plane → v × B points along y-axis .
کل داخلی عکاسی کا رجحان واقعات کے زاویہ کے لئے مشاہدہ کیا جاتا ہے؟
A. Greater than critical angle
B. None of these
C. Equal to critical angle
D. Less than critical angle
Check answer and explanation
Answer: Greater than critical angle
Explanation Total internal reflection occurs when light travels from a denser to a rarer medium, and the angle of incidence exceeds the critical angle . At this point, light is completely reflected back into the denser medium.

Explanation Cathode Ray Tubes (CRT) are used in old television sets and computer monitors . They work by directing electron beams onto a screen to create images.
اگر فاصلہ وقت کے ساتھ یکساں طور پر بڑھ رہا ہے، تو رفتار کیا ہے؟
A. Increasing
B. Decreasing
C. Constant
D. Zero
Check answer and explanation
Answer: Constant
