Question

what is the mass of a body on which a force of 300 dynes produces an
acceleration of 30 m/s2 is
1) 10 x 10-5 kg
10 kg 2) 1 * 10-4 kg 3) 1 x 10-5 kg 4) both (1) & (2)​

Answer 1

Answer:

3) 1*10^-4 kg

Explanation:

F = m.a

here, F=300dyn = 300/10^5 [ as, 1 N= 10^5 dyn] and. a= 30 m/s^2

so, m= F/a= 300/10^5 × 1/30

= 1/10^4

=1 × 10^(-4)
