The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Electric Field Intensity**: Electric field intensity (E) at a point in space is defined as the force (F) experienced by a charge placed at that point. 2. **Identifying the Charge**: The charge that experiences this force is typically a unit positive charge, which is often referred to as a "test charge." 3. **Defining the Relationship**: The electric field intensity can be mathematically expressed as: \[ E = \frac{F}{Q} \] where: - \(E\) is the electric field intensity, - \(F\) is the force experienced by the charge, - \(Q\) is the magnitude of the charge (in this case, a unit positive charge). 4. **Filling in the Blanks**: Based on the definition, we can fill in the blanks in the question: - Electric field intensity at any point is the **force** experienced by a **unit positive charge** placed at that point. 5. **Final Answer**: Therefore, the complete statement is: - Electric field intensity at any point is the **force** experienced by a **unit positive charge** placed at that point. ---

    Electric field intensity at a point a hollow charged spherical conductor

    Assertion: If there is a system of two unequal point charges of any polarity then there is one and only one point in space around it where the electric field intensity is zero. Reason: The direction of electric field intensity at a point is away from the positive charge and towards the negative charge, along the line joining the charge and location where electric field intensity is to be calculated.
