Consider the following statements:
(1). There are chances of toppling when a truck takes a sharp turn specially when it is fully loaded because it increases the rotational force.
(2). While throwing a ball upwards, the velocity remains the constant.
Which of the given statements is /are correct?
-
Only (1)
-
Only (2)
-
Both (1) & (2)
-
Neither of these
D
Correct answer
Explanation
Statement (1) is wrong. When a truck is fully loaded, its centre of gravity will be raised making it unstable. When taking a sharp turn the vertical line through the centre of gravity will fall outside the base of support, and the truck may topple over.
Statement (2) is also incorrect. While throwing a ball upwards, the acceleration remains the constant.
