If a force `vecF = 3hati - 4hatj N` produces an acceleration of `10 ms^(-2)` on a body, then the mass of a body is

10 kg

9 kg

0.9 kg

0.5 kg

Text Solution

Verified by Experts

The correct Answer is:

`vecF = 3 hati - 4 hatj N`
magnitude : `|vecF| =sqrt(9 + 16) = sqrt25 ` = 5N
`F = ma rArr m = (|F|)/(a) = 5/10 = 1/2 = 0.5 kg `
