Question

charge A +1c , B+2c , C +1c , amd D +1c are placed at corners of square what will be the force on D

​

Answer 1

Answer:

9×10^9(2^1/2 +1)

Explanation:

plz see the photo it will definitely helpful

Answer 2

Explanation:

Force on D due to A = k*(1*1)/1² = k .....(i)

Force on D due to B = k*(2*1)/(√2)² = k.....(ii)

Force on D due to C = k*(1*1)/1² = k......(iii)

Therefore the net force on D = (i) + (ii) + (iii)

= k+k+k

= 3*k

= 3*(9*10^9)

= 27*10^9

= 2.7*10^10.
