12 A particle, under the action of two constant forces, is moving across a perfectly smooth horizontal surface at a constant speed of \(10 \mathrm {~m} \mathrm {~s} ^ { - 1 }\)
The first force acting on the particle is \(( 400 \mathbf { i } + 180 \mathbf { j } ) \mathbf { N }\).
The second force acting on the particle is \(( p \mathbf { i } - 180 \mathbf { j } ) \mathrm { N }\).
Find the value of \(p\).
Circle your answer.
\(- 400 - 390390400\)
