Question

charge each of +3micro coulomb at placed at three corners of a square whose diagonal is 6 cm long .Electric field intensity at the point of intersection is​

Answer 1

Answer:

3×10*7 N/C

Explanation:

Suppose 3 charges r positive nd one as negative then one negative nd one positive cancels each other therefore we got 2 positive repelling each other by same force nd thus we have to find out by only one charge .

E=Kq/r*2

E = 9×10*9 × 3×10*-6 / 0.03*2

E = 3×10*7 N/C

r is taken as half of diagonal as point of intensity is at the centre of square .
