An electric dipole consists of two opposite charges each of magnitude` 1 mu c ` separated by 2 cm. The dipole is placed in an external electric field of ` 10 ^(5) N C ^(-1)`
Find
The maximum torpue exerted by the field on the dipole

Text Solution

Verified by Experts

Given:
` p = q xx 2 l = 10 ^(-6) xx 2 xx 10 ^(-2) = 2 xx 10 ^(-8) cm
E = 10 ^(5) NC^(-1)`
`tau _("max") = "p E sin " 90^(@) = 2 xx 10^(-8) xx 10 ^(5) xx 1 `
`= 2 xx 10 ^(-3) ` Nm
