Answer 1

Force=62.5 N

Hope it helps u....

Answer 2

Explanation:

$\tt Question\:B \\ \\ \tt Work\:done\:(W) = 4\: kiloJoule = 4000 \:Joule\\ \tt Displacement\:(s) = 64\:m \\ \\ \tt We\:know\:that \\ \\ \tt W = F.s \\ \\ \tt F = \frac{W}{s} \\ \\ \tt F = \frac{4000}{64} \\ \\ \tt F = 62.5 \:N \\ \\ \boxed{\bold{\red{\underline{\tt Force\:acting\:on\:body\:is\:62.5\:N}}}}$
