                rb.Addforce(500*Time.deltatime, 0, 0);

Answer 1

As per comment above - your if statement should look like this:

if (Input.Getkey("d"))

{
      rb.Addforce(500*Time.deltatime, 0, 0);
}

Usually an IDE should point it out for you.

Answer 2

You made a mistake right here:

if (Input.Getkey("d")

        (
            rb.Addforce(500*Time.deltatime, 0, 0);
        )

You used (), instead of {}. There is a simple solution:

Use after the statement {}

.

if (Input.Getkey("d")

        {
            rb.Addforce(500*Time.deltatime, 0, 0);
        }
