Two point charges Q and - Q //4 are separated by a distance X . Then .

The force between two charges 9 mu C and 1mu c separated by a distance 3 m in space is..........

An electric dipole consists of two opposite charges each of magnitude 2 muC separated by a distance 1 cm. The dipole is placed in an external field of 10^(3) N/C. The maximum torque on the dipole is

An electric dipole consisting of two opposite charges of 2xx10^(-6)C each separated by a distance of 3 cm is placed in an electirc field of 2xx10^(5)N//C . The maximum torque on the dipole is will be

An electric dipole consists of charges pm 2.0 xx 10^(8) C separated by a distance of 2.0 xx 10^(-3) m. It is placed near a long ilne charge of linear charge density 4.0 xx 10^(-4) C m^(-1) as shown in figure (30-W4), Such thet the negative charge is at a distance of 2.0 cm from the line charge. Find the force acting on the dipole.
