Final answer:
A positively charged sphere will move towards negative charges due to the attraction between opposite charges, as described by Coulomb's Law. Option A is correct.
Step-by-step explanation:
The question refers to the behavior of a positively charged sphere when it is released from rest. According to the principles of electrostatics, a positively charged object will experience a force due to its interaction with other charges. Specifically, it will be attracted to negative charges and repelled by other positive charges as described by Coulomb's Law.
In this situation, option A) 'The sphere moves towards the negative charges' is correct because positive and negative charges attract each other. This is consistent with electrostatic attraction, where opposite charges attract. Therefore, if the sphere were placed in an environment with both positive and negative charges present, it would move towards the negative charges.
The small sphere with a positive charge will move towards the negative charges.
When a positive charge is released, it experiences a force in the direction of the electric field, which is from positive to negative charges.
Therefore, the correct answer is Option A) The sphere moves towards the negative charges.
