There are two charges and The ratio of forces acting on them will be

There are two charges \( +2 \mu C \) and \( - \) \( 3 \mu C . \) The ratio of forces acting on them will be

  • A. 2: 3
  • B. 1: 1
  • C. 3: 2
  • D. 4: 9

Step-by-step solution

According to Newton's third law of motion, the force on charge +2 μC due to -3 μC is equal in magnitude and opposite in direction to the force on -3 μC due to +2 μC. Therefore, the ratio of forces acting on them is 1:1.
