चार बिंदु आवेश `q_(A)=2 mu C, q_(B), q_(c)` तथा `q_(D)=-5 mu C 10 cm` भुजा के किसी वर्ग ABCD के शीर्षो पर स्थित है । वर्ग के केंद्र पर रखे `1 mu C` आवेश पर लगने वाला बल कितना है ?

Four point charges q_(A) = 2 mu C , q_(B) = -5 mu C, q_(C) = 2 mu C and q_(D) = -5 mu C are located at the corners of a square ABCD of side 10 cm. What is the force on a charge of 1 mu C placed at the center of the square ?

A circle is inscribed in a quadrilateral ABCD , touching sides AB , BC , CD and DA at P , Q , R , and S respectively. If AS = 8 cm , BC = 11 cm and CR = 5 cm, then the length AB is equal to : एक वृत्त किसी चतुर्भुज ABCD के भीतर स्थित है जो भुजा AB, BC, CD तथा DA को क्रमशः P, Q, R और S पर स्पर्श करता है | यदि AS = 8 सेमी, BC = 11 सेमी और CR =5 सेमी है, तो AB की लंबाई ज्ञात करें |

Four point charges q_(A) =2 mu C ,q_(B )=-5 muC,q_(c )=2 mu c and q_(d)=-5 mu c are force on a charge of 1 mu c placed at the centre of the square
