Two small balls having equal positive charge Q (Coulomb) on each are suspended by two insulating strings of equal length 'L' metre, from a hook fixed to a stand. The whole set up is taken in a satellite in to space where there is no gravity (state of weight lessness) Then the angle (q) between the two strings is
  • a)
  • b)
    90º
  • c)
    180º
  • d)
    0º < q < 180º
Correct answer is option 'C'. Can you explain this answer?

There is a condition of weightlessness in a satellite.
Therefore, mg=0
Due to electrostatic force of repulsion between the balls, the string would become horizontal.
Therefore, angle between the string =180

B)90°
c)45°
d)60°

Answer: a) 0°

Explanation:

In the absence of gravity, the two small balls will remain stationary at the same position. The strings will not experience any tension or force due to gravity.

Since both the balls have equal positive charge, they will repel each other with equal force. This force will act along the line joining the two balls.

As a result, the strings will become parallel to each other. The angle between them will be zero degrees.

Therefore, the correct answer is option a) 0°.
