Class 12th

yes, Interior designing courses after 12th are available as certificates, diplomas in interior design, and undergraduate courses.

Some of the popular courses are :

• Diploma in Interior Design
• BDes Interior Design

Not really. The electric dipole moment vector directs or points from the negative charge to the positive charge. But the electric field lines that a dipole creates will point away from the positive and move to the negative charge.

Yes, the cube, which is a closed surface containing only one electric dipole will make electric flux zero. This follows Gauss's Law when the total charge inside it is zero. The field lines entering the surface will exit, and that would result in zero net flux. 

The magnitude of each charge and the distance that separates them. 

There are various important topics in the physics chapter 5 class 12 magnetism and matter. These topics are important for both cases, conceptual and numerical questions. Read below:

• Magnetism 
• Bar Magnet as an Electromagnet
• Magnetic Field Due to Magnetic Dipoles
• Type of Magnetic Materials: Ferromagnetic, Paramagnetic, and Diamagnetic
• Magnetisation and Magnetic intensity
• Magnetic Susceptibility
• Magnetic Flux Intensity 
• Potential energy due to a magnetic dipole

To begin with, you can prepare for CLAT simultaneously as Class 12 if have a smart and consistent approach:

• Start early – Beginning of Class 12 to manage both studies.
• Daily Time – 2-3 hours you spend for CLAT preparation each day.
• Sections covered – English, Current Affairs, Legal Reasoning, Logical Reasoning and Quantitative Techniques.
• Read daily newspapers like The Hindu or Indian Express.
• Keep taking mock tests to gain more speed and accuracy.
• Refresh weekly to reinforce soft spots.

Good material to refer from- either CLAT books or online test series and if necessary coaching.

Gauss Law is only concerned with the total enclosed charge that finally tells us the total flux. The charges outside may change field patterns. They not affect the total flux. It's actually incorrect to assume the field due to the external charges should also affect the flux through the Gaussian surface. 

Gauss Law does not directly give the electric field in all cases. It can only be used in calculations for symmetrical surfaces: spherical, cylindrical, or planar.
