Show Hint
The formula for gravitational potential energy is \( PE = mgh \). Ensure that the height is measured from a reference point (e.g., ground level).

\( 49 \, \text{J} \)
\( 98 \, \text{J} \)
- \( 196 \, \text{J} \)
- \( 10 \, \text{J} \)
Show Solution
The Correct Option is B
Solution and Explanation
Gravitational potential energy is calculated using the formula \( U = mgh \). The parameters are defined as follows: \( m = 2 \, \text{kg} \), \( g = 9.8 \, \text{m/s}^2 \), and \( h = 5 \, \text{m} \).
Substituting these values yields: \( U = 2 \times 9.8 \times 5 = 98 \, \text{J} \).
Correct Answer:
Option 2: \( 98 \, \text{J} \)

- A curve is given between the potential energy \(U\) of a particle and its position on the \(x\)-axis as shown. Given: \[ \tan\theta_1 = 1,\qquad \tan\theta_2 = 3,\qquad \tan\theta_3 = -\frac{1}{2} \] If \(F_{AB}\) is the force acting on the particle during motion from \(A\) to \(B\), similarly \(F_{BC}\), \(F_{CD}\) and \(F_{DE}\) are the forces during \(B\) to \(C\), \(C\) to \(D\) and \(D\) to \(E\) respectively, arrange the magnitudes of these forces in decreasing order.

- Given below are two statements:
Statement I: An object moves from position \( \vec{r}_1 \) to position \( \vec{r}_2 \) under a conservative force field \( \vec{F} \). The work done by the force is \[ W = -\int_{\vec{r}_1}^{\vec{r}_2} \vec{F} \cdot d\vec{r}. \]
Statement II: Any object moving from one location to another location can follow infinite number of paths. Therefore, the amount of work done by the object changes with the path it follows for a conservative force.
