An electric dipole consists of charges ±5.00 µc separated by 1.20 mm. it is placed in a vertical electric field of magnitude 525 n/c oriented as shown in the figure. the magnitude of the net torque this field exerts on the dipole is closest to

You can solve this problem by dimensional analysis, that is by merely cancelling out the units until you reach the units of the unknown measurement. for torque, its unit is n-m or joule. thus,

525n/c * (5 x 10^-6 c) * (0.0012 m) = 3.15 x 10^-6 joules

i hope i was able to . have a good day.
