Please help to solve this

Permission: Assignment - Only Group Members can read
Create a new file called myemptyfile. You can use:

touch myemptyfile
Check its permissions using:

ls -lh myemptyfile
Using chmod, give it permissions such that the owner of a file should be able to read and modify, members of groups can only read, others can’t read or modify.

Is it resolved?

I saw a similar discussion on the LMS.

Solved thank you very much
