Answer 1

Teacher asked to explain the law of gravitation.

Answer 2

Hi✋✋,

Here's ur answer:-

The teacher urged the student to explain the law of gravitation.

Here law of gravitation is a noun , hence it can't have any past tense but if we change explain to explained, it becomes irregular. So, the above sentence that I have written is correct.

HOPE IT HELPS ☺
