Question

please help out with this with steps

Answer 1

$\bold{Heya.....!!!}$


These questions are based on the formulae :-

$\huge\boxed{w=mg}$

$\huge\boxed{F = Gm1m2/r^2}$


Q.1)

→ Force of attraction is given to us = 40 N , and according to question the distance is halved
i.e => $\bold{F = Gm1m1/(r/2)^2}$

New force will be :

= $\bold{F = 4(Gm1m2/r^2)}$


→ 4 × 10 = 40 N



Q.2) $\bold{w = mg}$ here , m = 5 Kg and g = 10 m/s^2

=> Weight = 5*10 = 50 N






Q.3.)

→ We know that weight of body is =
【 w= mg 】 , here m = 10 Kg and g = 9.8 N , so just put values and take out the answer




Q.4.)

→ Force of gravity always acts in Downward direction . and it's magnitude will be
=> w = mg = 5*9.8 = 49 N
