Answer #1

(a) I have calculated the divergence in cartesian co-ordinates and then converted to spherical co-ordinates.

(b) This is also very straightforward question.

I have equated x-components in last part. You can also do this by equating y- and z- components.The answer would be same.

Hope you find it useful. Sorry for any calculation mistake. have a nice day :)
