Hey...
Both are good if you can progress upto Ph D; Physics professionals who have good knowledge in some area of Applied physics have the following options today - as Subject Matter experts in engineering organizations, Consultants and ofcourse teaching; It is very difficult to get a good physics teacher today;

Chem doctrates - there are more options - Analytical labs, Pharma organizations, Teaching; Consulting;

For both fields additional skills are required such as programming skills (C or C++); good knowledge of working with Statistical software;
Your potential lies in you

In which subject you can give your best ??

Answer to your question is you yourself

So Don't be silly with dilemma of scope

Go ahead with any of these with a strong determination

Scopes are diverse along with your knowledge ..

Choose according to your passion..

All the best ..

Hope this helps you!
Best wishes!
