A gravitational field is present in a region and a mass is shifted from \(A\) to \(B\) through different paths as shown. If \(\mathrm{W_1}\), \(\mathrm{W_2}\) and \(\mathrm{W_3}\) represent the work done by the gravitational force along their respective paths, then:
1. \(\mathrm{W}_1=\mathrm{W}_2=\mathrm{W}_3\) 2. \(\mathrm{W}_1>\mathrm{W}_2>\mathrm{W}_3\)
3. \(\mathrm{W}_1>\mathrm{W}_3>\mathrm{W}_2\) 4. \(\mathrm{W}_1<\mathrm{W}_2<\mathrm{W}_3\)

Given below are two statements: 
Assertion (A): When a firecracker (rocket) explodes in mid-air, its fragments fly in such a way that they continue moving in the same path, which the firecracker would have followed, had it not exploded.
Reason (R): Explosion of cracker (rocket) occurs due to internal forces only and no external force acts for this explosion.
 
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
