Question

require a greater force:- accelerading a 4kg mass at 5m/s² (or) 6 Kg mass at 3 m/s²​

Answer 1

Case-1:

$\pink{ \boxed{\boxed{\begin{array}{cc} \maltese \: \: \bf \: mass \: \: m = 4 \: kg \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \bf \: \maltese \: \: acceleration \: \: a = 5 \: m {s}^{ - 2} \\ \bigstar \bf \: \: Force \: \: \: F_1 \: = \: to \: find \: \: \: \: \: \: \: \\ \\ \sf \: we \: know \: that \: \\ \\ \bf \: F_1 = ma \\ = 4 \times 5 \\ = 20 \: N \: \end{array}}}}$

Case-2:

$\blue{ \boxed{\boxed{\begin{array}{cc} \maltese \: \: \bf \: mass \: \: m = 6 \: kg \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \bf \: \maltese \: \: acceleration \: \: a = 3 \: m {s}^{ - 2} \\ \bigstar \bf \: \: Force \: \: \: F_2 \: = \: to \: find \: \: \: \: \: \: \: \\ \\ \sf \: we \: know \: that \: \\ \\ \bf \: F_2 = ma \\ = 6 \times 3\\ = 18\: N \: \end{array}}}}$

Final answer :

$\red{\qquad \boxed{\boxed{\begin{array}{cc} \maltese \: \bf \: \: \: \: \: F_1 > F_2\end{array}}}}$
