A molecule of hcl dipole moment p 360times10-30 cm and

Question

Problem: A molecule of HCl (dipole moment p = 3.60×10^-30 Cm) and moment of inertia of 2.70×10^-47 kgm²) is suddenly subjected to an electric field E at right angles to the direction of the molecule's dipole moment. If the initial angular acceleration of the molecule is 2.93×10²¹ rad/s2,

Part A- What is the magnitude of the electric field?

It'd be really helpful if you could show all steps of your work for above problem.
