Question

products of reaction are

Answer 1

Please remember these points below which are helpful in doing problems of stereochemistry:

CAR - cis on anti addition gives a racemic mixture.
TSR - trans on syn addition gives a racemic mixture.
CSM - cis on syn addition gives meso compounds.
TAM - trans on anti addition gives meso compounds.

Coming to your question,
The reactant is in cis configuration, which when reacted with Br2 implements anti addition to it, thus giving a racemic mixture.

It is advised to remember about what compounds do what addition(syn or anti)

Answer 2

It all depends on the stereochemistry of the substrate!
