Hii,

Computer Science Engineering is one of the Best Branches in the Engineering field. It doesn't deal with Physics. In the first year of Btech Every student has to write Physics Exam irrespective of the Branch. That is very basic which you have learnt in the previous years. No worry about that. After that you won't deal with any science related subjects in CSE stream. So choose CSE. The Job opportunities are also very high for this Branch. 

Hi,
Choose your branch wisely you need to see your area of interest.
If you are not good in physics then don't choose mechanical branch as it requires a lot of concept of physics.
If you are good in mathematics then you may go for Cs and Ec branch.

There are no “branches” of engineering without physics. It is a question of “how much physics”.

In first year of engineering you will have to go through the physics whatever your branch is. If you are having CSE or IT then it may reduce the portion of physics ……but thinking power is the need like a physics student, 
best wishes.
