Answer: will lie above the marginal product curve for the firm with less capital.
Explanation:
Capital is needed to produce goods and services and ideally speaking, when more capital is invested, more goods and services will be able to be produced because more should bring in more.
It is the same case here, if the companies are similar in everything except capital invested, the company with more capital will be able to produce more goods and services which will lead to their marginal product curve lying above the marginal product curve of the company with less capital.
