# A water molecule perpendicular to an electric field has more potential energy than a water molecule aligned with the field. The dipole moment of a water molecule is . What is the strength of the electric field?

The electric field's magnitude is.

See the step by step solution

## Step 1: Given Information

Given:

• The potential energy of a water molecule perpendicular to an electric field is higher than that of a water molecule aligned with the field.
• Dipole moment,

## Step 2: Determine the electric field strength

A water molecule aligned with the field has more potential energy than a water molecule perpendicular to the field.

Compute the water molecule's potential energy perpendicular to the electric field.

Estimate the water molecule's potential energy when it is aligned with the electric field.
