To understand the reason behind is, you can imagine that circular ring is nothing but will behave like a charge if we compare it to heavy bodies such as moon or earth
- 22) A sphere with radius 2.0 mm carries a +2.0 µC charge. What is the potential difference, VB - VA, between point B, which is 4.0 m from the center of the sphere, and point A, which is 6.0 m from the center of th
- The formula that gives electric potential is . 1) At point a, the electric potential is the sum of the potentials due to q1 and q2. So, The distance from the center of the square to one of the corners is . The answer is zero, because the point charges are at equal distances and their magnitudes are also equal but their directions are opposite. 2

**point****charges**q 1, q 2, q 3, and q**4**are as shown in figure. The flux over the shown Gaussian surface depends only on**charges**q 1 and q 2. Reason:**Electric**field at all**points**on Gaussian surface depends only on**charges**q 1 and q 2, Answer: (d) Assertion is incorrect, reason is correct. Question 2. Assertion - 51) Point charges +4.00 μC and +2.00 μC placed at : 1178871. 51) Point charges +4.00 μC and +2.00 μC are placed at the opposite corners of a rectangle as shown in the figure. What is the potential at point A, relative to infinity, due to these charges? (k = 1/4πε0 = 8.99 × 109 N ? m2/C2) C) 89.9 kV
- • [Electric potential] = [energy]/[charge] SI units: J/C = V (volts) • U E (r) of a test charge q 0 in electric field generated by other source charges is proportional to q 0. 0 () E Ur Vr q {taking the same reference point Potential energy difference when 1 C of charge is 1 J moved between points of potential difference 1 V Scalar

- Hence potential due to one charge Field = zero. Question 14. Two tiny spheres carrying charges 1.5 μC and 2.5 μC are located 30 cm apart. Find the potential and electric field (a) at the mid-point of the line joining the two charges, and (b) at a point 10 cm from this midpoint in a plane normal to the line and passing through the mid-point.
