Physics is a core science subject that deals with the study of matter, energy, motion, force, heat, light, electricity, magnetism, and modern physics concepts. It plays a vital role in competitive exams such as PPSC, FPSC, NTS, OTS, KPPSC, BPSC, AJKPSC, CSS, and PMS, where questions test conceptual understanding, numerical problem-solving, and application of laws and formulas.

A at2/2
B Vt
C a2t/2
D at2
Correct Answer: at2/2

When two bodies move toward each other with constant speeds the distance between them decreases at the rate of 6m / sec. If they move in the same direction the distance between them increases at the rate of 4m/sec. Then their speeds are________________?

A 5m/s, 1m/s
B 3m/s, 3m/s
C 6m/s, 1m/s
D 4m/s, 2m/s
