Husband on B1 and wife on B2

[Seshasai]

Hi, I have a valid B1 multiple entry visa. I forsee a business trip for 10 days to US and would like to take my wife for that time by applying a tourist B2 visa for her.
Now, she was already married once and during that time travelled to US on a H4 visa. This was 3 years back.
Will they ask her any questions regarding this while obtaining her tourist visa?
She is a housewife now. What proof can she show for binding ties in India to get her B2 visa easily?

They might ask her questions about her H-4 stay in the US. Should not be a show stopper on its own.
She needs to show proof of financial and social ties to India. In other words, ties strong enough to convince the consul that she will return to India in a timely fashion.
