a. Trọng lượng của vật là:

P=10.m= 10.15=150N

Trọng lực có phương thẳng đứng, chiều từ trên xuống dưới.b. c.Trọng lượng của vật là:

P= 10.m= 10.6=60N

Trọng lượng có phương thẳng, đứng chiều từ trên xuống dưới.

Vì vật đang đứng yên, nên chứng tỏ đã có 2 lực cân bằng tác dụng vào vật. Đó là trọng lực và lực nâng (P = Q)
