JEE Main 2026 Physics question
At t=0, a body of mass 100 g starts moving under the influence of a force (5î+10ĵ) N. After 2 s its position is (2xî+5yĵ) m. The ratio x:y is .
Answer: (D)
Solution
a = F/m = (50,100) m/s². Starting from rest, s = ½at² = (100,200) m at t=2s. So 2x=100 (x=50) and 5y=200 (y=40); x:y = 5:4.
